Chainsaw 101: Chain Types and Sizes

Today, there are almost limitless combinations of sizes, types, and features for chainsaw chains. There are just several available varieties on the market, which is because chainsaws themselves also come in several varying sizes and applications.

Chainsaw chain types:

• Aggressive (Full-Skip)
• Regular Chains (Skip-Tooth)
• Low-Kickback/Anti-Kickback
• Ripping Chain
• Narrow Kerf Chain
• Low Profile Chainsaw Chain

Chainsaw chain sizes:

• Pitch Measurement
• Gauge Measurement
• Number of Drive Links

If you want to replace your chainsaw chain, you need to have all the appropriate information as regards your chainsaw and its chain size or types. It can be somewhat easy to match the right chain to a chainsaw if you have the right information or measurements. However, this can also become a little more complicated, even more than finding your power tool accessories, because of the unique way that chainsaw chains are usually measured.

Chainsaw 101: The Ultimate Guide

Even after matching the right size of chain for your chainsaw, there are still loads of chainsaw chain types, and features that you can choose from that would be a match to the application. However, these features and types are usually much more straightforward than finding measurements. Before we go into the various types and features of a chainsaw chain, let us look at the measurements, which are absolutely important for matching chainsaw chains. It is critical to know that there are three major measurements that every chainsaw user needs to know ahead of time to ensure that the appropriate chain size matches their chainsaw. They include the Pitch, Gauge, and the number of Drive links(they must be counted).

Here is an in-depth explanation of how these features are measured on chainsaw chains, the most common measurements that are used, the method of how to find these measurements, and how to measure them even when they cannot be found. 

1. Pitch Measurement:

The pitch measurement of a chainsaw chain shows how close to each other the links are on the chain. The pitch does not describe the total number of links present on the chain; neither does it give details of the total length of the chain. Instead, the pitch is half of the distance between any three (3) rivets on the chain. Although this measurement is quite complicated, most chainsaw manufacturers display the measurement either on the tool or in the user manual for ease. The following pitch sizes are available on chainsaw chains, and they are usually measured in inches: 1/4 inch, 0.325-inch, 3/8 inch, 3/8 inch low profile, and 0.404-inch.

The 3/8 inch pitch size is usually the most common size of the pitch chain, followed by the 3/8 inch low-profile pitch chains, which are even more common than the regular 3/8 inch chains. These 3/8 inch low-profile chains allow only a small amount of the material to be cut. This is because the “kerf” (the width of material removed during cutting) is very narrow, reducing the power needed for cutting. The 3/8 inch low-profile chains are typically fit to chainsaws with guide bars that are 18 inches or lesser, which are the most commonly used chain for light, non-professional application chainsaws like one that a homeowner might own.

Now the 0.404-inch pitch chains are normally used for larger, professional-grade chainsaws like the ones that are used by professionals such as firemen and rescue workers. The distance between the links is very great and this gives room for more aggressive cutting.

When displayed on the tool, the chainsaw chain’s pitch measurement is usually on the guide bar and is located around the user-end of the tool. The measurement is sometimes displayed very clearly, and other times it is mixed in with other numbers. Therefore, you need to know what you are looking for. If a pitch size number cannot be found on the chainsaw or in the user manual, then the pitch can be measured. However, a high level of accuracy is needed when measuring to tell the difference between certain sizes (for instance, 0.325-inch and 3/8 inch), so it is advisable to take the saw to an expert for it to be measured.

However, if you still think you can measure the pitch by yourself, always remember to measure between the middle points of 3 rivets on the chain, then divide the result by 2. For example, if you measure a 3/8 inch pitch chain, the right measurement between 3 links would be 3/4 inch, which, when divided by 2, will give 3/8 inch.

2. Gauge Measurement:

There is a part of the chainsaw chain that fits into the guide bar. This part is called the drive links, and the drive link is the bottom area of the chainsaw chain. Now the gauge measures the thickness of the drive links when you look at them along the length of the chain. Certainly, it is very important to make sure that the right chain gauge is matched with the saw so that the chain can fit into the guide bar properly.

There are several gauge measurements available for chainsaw chains, all of which are also measured in inches, and they include the following: 0. 043-inch gauge, 0.050-inch, 0.058-inch gauge, and 0.063-inch gauge. The 0.050-inch is the most common gauge measurement. Just like the pitch measurement, the gauge measurement is also usually displayed on the chainsaw, often towards the user-end of the guide bar. The gauge measurement, also like the pitch measurement, can either be displayed clearly on the tool or mixed with a bunch of other numbers. Therefore, it is also important to know the kind of numbers to look out for.

Since gauge measurements are very small, we do not recommend that users measure gauge by themselves (if the measurement cannot be found on the tool or in the user manual). Rather, it should be taken to a store for proper and accurate results. However, if accurate calipers are available, then the gauge measurement should not be hard. If calipers are not available to you, we recommend that you take the saw to a shop to have the chain gauge measured (there are even some tool men who are so familiar with these chains that they will be able to identify the measurements just by sight).

3. Number of Drive Links:

The number of drive links on the chain must be counted so as to get the right chainsaw chain (if the count is not already known). The overall length measurements of chainsaw chains (like “a 2-foot chain”) may not be helpful enough when you need to find the right chainsaw chain. This is because the total length of a chainsaw chain is given as a combination of both the pitch (distance between links) and the number of drive links. This method is the most accurate and best way for chain manufacturers to keep all the various sizes and types of chains in order. Normally, unlike the pitch and gauge, the number of links on a chain is not displayed on the tool or given in the manual. This is why the number of links on a chain must be counted.

Chain-Matching Search Steps

Before you begin a search for a matching chainsaw chain, it is important to go through some steps to get accurate results. Here are some steps that should be taken into consideration before you begin a search for a chainsaw chain that matches your chainsaw:

• Get the pitch measurement of the chain: This can be done either by finding it on the user end of the tool, in the user manual, or by dividing the distance between 3 links on the chain by 2. We recommend that this should be done by an expert in a shop.
• Get the gauge measurement of the chain: As stated above, this can either be done by finding it on the use ends of the tool, in the user manual, or by measuring the thickness of the chain’s drive links with a very accurate pair of calipers.
• Get the accurate number of each drive link on the chain: To get this, you need to count the number of drive links on the chain.

Now, if you have carried out the steps above, the rest is easy. As long as you have those three numbers, getting the right match of a replacement chain becomes easy, and this only takes a moment.

Types of Specialty Chains

Over the years, several types of chainsaw chains have been created to make cutting and sawing faster, easier, and to be best suited for a specific job. There are three types of specialty chains that are common. These include the Low profile chain, the Narrow kerf chain, and the Ripping chain.

● Low Profile Chainsaw Chain

A low profile or “lo-pro” chain makes use of cutters that aren’t as tall as those cutters on the standard chainsaw chain. This means that a low-profile chain will make a shallow cut. Some advantages come with using a low profile chain, one of which includes the weight. Normally, a low-profile chain weighs less than the standard chain, making it a good option for low-horsepower saws and electric saws. Hence, the lighter the weight of the chain, the less the strain on the engine.

Generally, low profile chains are available in a 3/8 inch pitch and a .050 inch gauge, and it fits bars that are specifically made for low profile chains. Now, if your chainsaw uses a bar that requires more than 72 drive links on its chain, then the low profile chain cannot fit and will not work with your bar and saw.

● Narrow Kerf Chain

The narrow Kerf chain has narrower cutters than the standard chain, just as the low profile chain has shorter cutters than a standard chain. If you use a narrow kerf vision, then you would get a thinner, narrower cut.

Since the cuts are thinner, the narrow kerf chain typically removes less wood than a standard chain when cutting. However, this feature allows the chainsaw to cut very quickly and to use a long bar with a full-size chain even if it is a low-horsepower saw that is being used. A narrow kerf chain is usually an excellent choice for electric chainsaws.

Just like the low profile chain, a narrow kerf chain might be available under a different brand name, such as Husqvarna’s Pixel chain, and some narrow kerf chains are also low profile chains that can help you achieve the same lightweight, high-speed cutting experience. Before you change, therefore, always look out for the compatibility of your narrow kerf chain to know if it matches your saw and its bar. Your bar must be like a bar created to fit a narrow kerf chain.

● Ripping Chain

Both the low profile chain and narrow kerf chain can help when you need to do standard tasks efficiently. For example, tasks like trimming tree limbs, cutting branches into smaller logs, and more can be done effectively with the low profile chain and narrow Kerf chain. In contrast to this, the ripping chain is designed for specific heavy-duty tasks such as milling logs into wood planks.

The cutters on the ripping chain can cut at an angle lower than those on standard chainsaw chains (10 degrees compared to the standard 30 degrees). Unlike the standard chains that cut against the grain of the wood, the ripping chain cuts along the wood’s grain. Because of this, the ripping chain can remove smaller chunks of wood less aggressively. This feature makes it the best option for creating finer cuts and smooth planks, explaining why its price is high. The ripping chain can be an essential investment, especially if you plan to use a portable sawmill with your chainsaw to mill logs.

Chain Aggressiveness

Chain Aggressiveness is a very important feature to consider before you purchase a new chainsaw chain. This fracture comes in three different levels or degrees. They are:

1. Low-Kickback/Anti-Kickback
2. Regular (Skip-Tooth), and
3. Aggressive (Full-Skip)

● Low-Kickback/Anti-Kickback

Most chainsaw chains are designed to have low-kickback or anti-kickback features that help to reduce the risk of kickback-related accidents. A kickback is a phenomenon that happens when the upper nose of your chainsaw guide bar makes contact with the material you are cutting during operation. This upper part of the chainsaw guide bar is often referred to as the “Kickback Danger Zone” because if it makes contact with the material during an operation, the increased resistance force will instantly throw the chainsaw back, which is in the direction of the user. Kickback-related accidents are usually terrible and gruesome, and the victim might end up visiting the hospital.

To avoid any damage or injury to the user, manufacturers have designed caution information to help their users. In addition, other online stores provide caution information that often appears at the top of their “Chainsaw Chains” Accessories page to help protect their users against accidents. However, while many chainsaw chains can kick back at any point of use, many others lack kickback protection and are only designed for professionals and experts. Therefore, if you have not received any specialized training for kickback control and prevention, you should only look into and purchase “Low Kickback” chains to help prevent injury or accidents.

However, low-kickback chains often limit the amount of material being cut and may be time-consuming. Hence, the cutting proceeds at a slower pace than with more aggressive chains. Even at that, low-kickback chains still require less power for cutting because of their narrow kerfs. For ease of purchase and to avoid confusion, it is also vital to note that most chain manufacturers have their own trademark names for the low-kickback designs available for their chains.

● Regular Chains (Skip-Tooth)

Skip-tooth chains are usually made to have a one-link space between each cutting tooth. This feature allows lower resistance, faster and grittier cutting. If the manufacturers do not list your chain as a low-kickback chain, a full-skip, or as having some other special feature, then it is most likely a regular skip-tooth chain that is often used for professional operations.

● Aggressive (Full-Skip)

A full-skip chain is designed in a way that it spaces two links between each cutting teeth, hence providing really low-resistance cutting. These chain types are usually for saws that have guide bars of 24 inches or more. After being trained properly to use the chains and saws of this particular length and cutting aggression, the users often enjoy the extra length because they don’t need to bend down to reach the work area. However, asides from the special convenience that they provide, these chains are often for trained and professional users, and a lot of regular chainsaw users will not have an application that requires this type of chain.

Chainsaw chain features

There are several other chainsaw chain features that are available and are equally important. There are also certain numbers of chain features that are offered for different sizes and types of chains. These features usually have trademarked names, which are given by the manufacturers. However, those features will be listed here according to their functions and properties.

1. Self-Sharpening Chains:

Self-sharpening chainsaw chains are designed with features that allow the teeth to file themselves as the chain passes around the guide bar. According to statistics, sharpening is one of the biggest maintenance problems that chainsaw users face, and it is usually best done by experts to avoid ruining the blades. Using a self-sharpening chain can actually help you to reduce those trips to a chainsaw store and also save costs. However, it is key to know that this feature does not always sharpen the chain completely. This is why the teeth should occasionally be touched up first, manually before needing to receive regular sharpening maintenance. However, the self-sharpening chain features will still make sure the chain remains sharper for a longer time.

2. Built-In Lubrication:

Chainsaws are designed to have many design features that would help keep the chains lubricated during operations. These features usually include grooves and holes in the cutting links, ensuring that the lubricant stays on the chain during cutting. Constant lubrication is obviously an essential maintenance method for any moving cutting tool such as a chainsaw. Hence, users should try to consider this feature, especially if maintaining proper lubrication through regular means feels like a hassle to them.

3. Low-Vibration Chains:

Both chainsaws and the chains receive vibration ratings from standardized testing. These ratings are quite important because constant use of vibrating tools such as chainsaws can cause serious health dangers to the hands or elbow (including pain, white finger syndrome, numbness, burning sensation, etc.) To tackle this problem, many chain manufacturers provide necessary design features that can greatly reduce vibration, and ultimately the risk of health problems. They can accomplish this by creating a space between the chain and the guide bar, which acts as a resistance against friction, reducing vibration. Chainsaw vibration should not be of much concern to users if they operate the saws only for occasional uses. However, if using the saw as part of your daily routine, then a low-vibration chain is the perfect option.

4. Ripping Chains:

Most users searching for chain types would certainly have run into this. Ripping chains are usually for a very specialized and professional operation that involves the cutting lengths of wood along the grain. Ripping chains are not for standard regular or normal applications because they require extra skills and techniques.

5. Carbide Chains:

Carbide is a type of material that is extremely hard and durable. Although it is quite brittle, carbide can shatter if it is struck with force. Now certain chainsaw chains are made with carbide. These chains are designed to have more durability, especially in cutting situations that should quickly and totally wear out a normal chain. However, these chains can be costly compared to the normal types, so they are usually only considered for operations in the dirt, sand, cold weather, and other extreme conditions that would normally cause wear to a chain. Although the durability of the carbide chain can keep the chain sharp for longer periods and helps prevent wear, this feature still results in a trade-off because carbide chains are usually less sharp and are slower during overall cutting. 

Are Chainsaw Chains Interchangeable?

It is somewhat impossible to give a direct answer that fits all types of chainsaws. Whether or not the chainsaw bars you’re planning to purchase will be interchangeable depends on many factors, which include the model of chainsaw that you have, the size of the bar, and more. Another way that might help is by assuming that you probably won’t take a particular brand of a chainsaw and use a bar from another brand on it. However, you might be able to use what is considered a universal chainsaw bar, that is, one that is not related to a name brand but can still suit your needs. Even after doing that, there are still certain things that you have to consider for you to determine if the chains are interchangeable or not.

• Consider the size: If you are going to be using the same chain for two different chainsaws, they have to be the same size.
• Consider the tensioner hole: Chainsaws often have a tensioner hole that allows you to adjust the tension of the chain on the bar.
• There are also oil holes that are present in some models of chainsaws.

At any rate, all of these features must be identical on both chainsaws for you to be able to use the chain bar on either of them. So if the tensioner hole on your chainsaws does not line up, if the sizes are not the same, or if the bolt slot is not placed in the same length on both tools, it simply won’t work.

If you are sure that all these features actually match, then the next step is to remove the chains on one chainsaw and place it on the other one. Make sure it actually works for a while before concluding. If your chainsaw does not have any problems, then you know for sure that you can use that same chain for both of the tools.

Final Remarks

Because the chainsaw is just one type of power tool accessory, there are several things to understand about the chains. Once that can be understood, then you’re clear. We only hope this article has been able to help you regarding the maintenance of your chainsaw. Good luck!

Measuring the Pitch of a Chainsaw Chain: A Guide

In the world of chainsaws, determining the pitch of a chain is crucial. It’s important to understand that both metric and imperial measurements are used interchangeably. For instance, a chain pitch labeled as 0.325 inches translates to approximately 1.5 millimeters in the metric system.

Always strive to familiarize yourself with both systems, as this knowledge will prove useful for purchasing chains worldwide. The Handbook of Forestry published by Agricultural Engineers is an excellent resource to learn more about these measurements.

• A Closer Look at Chainsaw Chain Gauge Measurements

When discussing chainsaw chains, the term ‘gauge’ often pops up. This refers to the thickness of the drive links. While some common measurements, such as 0.050, 0.058, 0.043, and 0.063 inches are often mentioned, you should note that other gauge sizes, such as 0.0435 inches, are also available.

• Counting the Drive Links on a Chainsaw Chain: Ensuring Accuracy

Counting the number of drive links on a chainsaw chain is an important yet meticulous process. To avoid miscounts or other errors, it’s recommended to count each drive link individually. This will ensure the highest level of accuracy and assist you in determining the correct chain size for your chainsaw.

• Finding the Right Chainsaw Chain: Checking the Manual

The quest for a perfectly matched chainsaw chain is made simpler with the right information. It’s highly recommended to consult your chainsaw’s user manual or even reach out to the manufacturer for specific recommendations.

This is due to possible variations or specific requirements applicable to your particular chainsaw model.

• Exploring Specialty Chainsaw Chains

While there’s a plethora of chainsaw chains with features like self-sharpening abilities, built-in lubrication, low vibration, or ripping capabilities, you should also be aware of specialty chains.

One example is safety or rescue chains, designed specifically for use by emergency response teams. This variant is known for its enhanced durability and high performance, ideal for rescue operations.

• Interchangeable Chainsaw Chains: Evaluating Compatibility

Chain interchangeability is not as simple as it seems. It’s not just about the chain; a thorough compatibility check of the guide bar and other components, like the tensioner hole and oil holes on both chainsaws, is required.

Your chainsaw’s performance could be severely affected if all the components don’t fit together seamlessly.

• Leveraging Chainsaw Manufacturers’ Identification Systems

Lastly, I’d recommend utilizing the tool identification systems provided by some chainsaw manufacturers. These software programs or guides can help users select the appropriate chainsaw chain for a specific model based on different criteria or measurements.

• Wrapping Up

Choosing and fitting the right chainsaw chain can be a complex task, but it’s crucial for the optimal operation and lifespan of your chainsaw.

By understanding the pitch and gauge measurements, ensuring compatibility with your chainsaw, and making use of the available resources and systems from manufacturers, you can effectively eliminate any guesswork and confidently find and fit the appropriate chain.

For more information about chainsaw maintenance and operation, the Home and Garden Information Center of Clemson University offers helpful guides and articles.

• Chainsaw Chain Basics: Understanding Chain Measurements

To fully comprehend the intricacies of chainsaw chains, it’s beneficial to have a firm grasp of the key measurements: pitch, gauge, and drive links.

– Pitch Value: Half the Distance Between Three Rivets

The pitch is a number that represents half the distance between three successive rivets of the chain. This metric is vital as it provides information about the size of the chain. You’ll find the measurement expressed in inches which makes it a universally understood parameter.

Remember, shorter pitch values on your chainsaw chain typically result in smoother cutting but at a slower rate, while larger pitch values increase the speed but could result in rougher cuts.

– Gauge Value: The Thickness of the Drive Links

Another vital value necessary for understanding your chainsaw chain is the gauge, which refers to the thickness of the drive link. Like the pitch, this measurement is given in inches.

Crucially, ensure the gauge of your chain matches the groove of your chainsaw guide bar. Incorrect matching can lead to a poor fitting and may cause potential damage or risk.

– Drive Links: More Than Just Teeth

The drive links are the “teeth” on the underside of the chainsaw chain and play a vital role in the overall functioning of your chainsaw. The number of drive links is directly correlated to the length of the chainsaw chain. Therefore, accurate counting of the drive links is necessary to identify the correct chain length.

When you have determined all three measurements – pitch, gauge, and the number of drive links, you’ll successfully navigate the first step in identifying the right chainsaw chain for your needs.

• The Aggressiveness: Speed and Smoothness of a Chainsaw Chain

The efficiency of a chainsaw depends significantly on how aggressively its chain can cut through wood. Three levels of chain aggressiveness exist anti-kickback, skip-tooth, and full skip chains.

– Choosing the Right Chain: Anti-Kickback, Skip-Tooth, and Full Skip Chains

The most common chainsaw chain is the anti-kickback. As the name suggests, these chains help prevent potential kickback accidents, enhancing the safety of the chainsaw operation. They may cut slower, but your safety is assured.

Skip-tooth chains, on the other hand, possess spaces between each of their cutting links. This design boosts the cutting rate substantially, making them ideal for quick but rough cuts.

For large chainsaw users, the full skip chains are the best option. Known as the most aggressive chains, they have a significantly higher cutting speed than the other two types. However, they also require greater skills to handle.

• Gearing Up for Chainsaw Usage

Understanding the measurements and types of chainsaw chains ensures smooth and efficient operation whenever you need to replace a chain. You’ll be better equipped to choose a suitable chain tailored to the complexity of the task at hand.

For further information regarding chainsaw chain measurements and types, check out this comprehensive guide at Oregon State University Extension Service. You’ll gain more insights into the world of chainsaw chains and their utility.

Remember, understanding chainsaw chains is not just about choosing any chain that fits. It’s about selecting a chain that not only suits your chainsaw size but also perfectly aligns with the nature of your cutting job.

With this knowledge at your disposal, you are always assured of a safe and seamless chainsaw operation.

Understanding Different Chainsaw Chain Types and Features

One important consideration when choosing a chainsaw chain is the different types and features that are available. These include self-sharpening chains, chains with built-in lubrication, low-vibration chains, ripping chains, and carbide chains.

– Self-Sharpening Chains

Self-sharpening chains are designed to reduce the effort and time required for maintenance. They utilize specially designed teeth to sharpen themselves while they operate. Over time, this attribute can significantly extend the lifespan of your chainsaw.

– Chains with Built-In Lubrication

Chains with built-in lubrication features maintain optimal performance by reducing heat and friction during operation. By delivering oil directly to critical areas of the chain, these types of chains extend operational life and reduce wear and tear.

– Low-Vibration Chains

Low-vibration chains help to reduce user fatigue and provide a smoother cutting experience. This feature is particularly advantageous for those users who operate chainsaws for extended periods.

– Ripping Chains

Ripping chains are designed to make long, smooth cuts against the grain of the wood. These chains are popular among woodworkers who use chainsaws for milling lumber.

– Carbide Chains

Carbide chains are known for their exceptional durability and longevity. They feature rugged, hard carbide tips that can withstand the toughest of cutting conditions.

• Selecting the Correct Chainsaw Bar

It is important to note that not all chainsaw bars are interchangeable. Compatibility should be determined based on the model of the chainsaw, the size of the bar, and the alignment of the tensioner and oil holes.

The Oregon Guide Bar and Chain is a great resource for figuring out which bars are compatible with your particular chainsaw model.

Before purchasing a new bar, I recommend examining your existing bar and noting down its size, the location of the tensioner and oil holes, and the model of your chainsaw. Armed with this information, selecting a compatible chainsaw bar will be a straightforward process.

• Measuring Your Chainsaw Chain

Understanding the measurements of a chainsaw chain is crucial for matching the correct chain to your chainsaw. The three necessary measurements include pitch, gauge, and the number of drive links.

– Understanding Chain Pitch

Chain pitch is defined as the distance between any three consecutive rivets divided by two. This measurement gives insight into how closely the chain’s teeth are spaced.

– Understanding Chain Gauge

Chain gauge refers to the thickness of the drive link where it fits into the guide bar. This specification is crucial because a chain’s gauge must match the guide bar’s groove.

– Understanding the Number of Drive Links

The number of drive links in a chain refers to the number of teeth that fit into the chainsaw’s guide bar. This factor is important for ensuring that your chain fits snugly and operates safely.

Understanding Chainsaw Chain Size

For those unfamiliar with chainsaw maintenance, determining the proper chain size for your chainsaw can indeed be confusing.

However, with proper knowledge and research, you can find the chain perfectly matched to your chainsaw. This guide serves as an informative tool to properly measure and understand chainsaw chain sizes.

– Basic Measurements of a Chainsaw Chain

A chainsaw chain size can be determined by three specific measurements: the pitch, gauge, and the number of drive links.

The Pitch

The pitch is the distance between your chainsaw chain’s drive lugs, which also function as drive links. The easiest way to measure the pitch is by measuring every three rivets on your chainsaw chain and then dividing this measurement by two.

Most chainsaws commercial chainsaws use a pitch of 0.325″, 0.375″, or 0.404″, with 0.250″ as a less common size. Many consumer chainsaws often use a variation of a 0.375″ pitch called the low-profile chain.

The Gauge

The gauge of a chainsaw chain is the thickness or width of the chain’s drive lugs. The majority of chainsaws use a 0.050″ or 0.058″ gauge chain, while 0.043″ and 0.063″ gauge chains are less common.

Number of Drive Links

The number of drive links in a chainsaw chain is crucial in ensuring that your chainsaw has the correct sized chain. You can calculate the number of drive links by counting them from the chain you are replacing.

• Sharpening a Chainsaw Chain

Chainsaw chains indeed need regular sharpening to ensure optimal performance and safety. It’s crucial to sharpen chainsaw chains carefully to avoid any potential accidents during operation and ensure effective cutting after the sharpening process.

As you sharpen a chainsaw chain, please remember to remove all the material from the cutter, not just the top of the cutter. Additionally, Oregon University Extension provides an excellent guide on how to properly sharpen a chainsaw chain.

• Replacing a Stihl Chainsaw Chain

Stihl chainsaw chains have a unique proprietary marking system that includes the chain’s pitch, gauge, and other chain characteristics. If you’re replacing a Stihl chainsaw chain, consider looking at the Stihl Marketing Number System to ensure you’re getting the correct chain.

• Chainsaw Bar and Chain Size Chart

Utilizing a chainsaw bar and chain size chart can greatly aid you in finding the right chain for your chainsaw. These charts often list various chainsaw models from a multitude of brands. It details the corresponding chainsaw bar length, the chain size, and the number of drive links.

• Concluding Thoughts

Understanding how to accurately measure the size of a chainsaw chain can save you both time and energy. This guide provides a comprehensive source of essential tools, methods, and information needed to measure the chain size effectively.

Always ensure the accurate identification of your chainsaw’s pitch, gauge, and number of drive links before buying a new chain. Your chainsaw’s performance, effectiveness, and your safety heavily depend on the accuracy of these measurements.

Choosing the Right Chainsaw Bar and Chain

Chainsaws are handy tools in various settings, providing a vital service where manual saws and axes can’t get the job done. However, to ensure these tools are functioning optimally and safely, using the correct chainsaw bar and chain is crucial.

• Chainsaw Bars and Chains: Power and Size Parameters

The first thing you should know is that the chainsaw bars’ size is closely related to the power of the chainsaw itself. In general, larger bars are best suited for potent chainsaws with substantial horsepower. This correlation is due to larger bars requiring more power to cut through materials, which is only available in high-powered chainsaws.

For instance, electric chainsaws, which are generally less powerful than their gas-powered counterparts, usually utilize bars that are 18 inches or shorter. This size is optimal for these tools, considering their power limitations.

• Measuring Chainsaw Bar Length

Understanding how to measure your chainsaw bar length is vital in selecting the correct replacement bar. The measurement to consider is the usable length of the bar, not the overall length.To do this, measure from the bar’s front tip to the point closest to the cutter – the chain tooth that does the cutting.

Once you’ve obtained the measurement, round it up to the nearest even number in inches. This measurement constitutes your bar length, which is critical when purchasing a replacement bar.

• Determining Chain Size

Once you’ve settled on the chainsaw bar, the next step is to determine the chain size. The two key measurements here are the chain’s pitch and gauge.

The pitch refers to the distance between the chain’s links. Specifically, it’s the length between three consecutive rivets divided by two. The two standard pitches you’ll often come across are 3/8 inch and .325 inch.

To determine the chain gauge, you can use an efficient and easy method using coins. Chain gauge relates to the width of the groove where the chain fits into the chainsaw bar. By placing different coins into the groove, you can determine the correct gauge.

Usually, a penny fits .063 gauge, a dime fits .050 gauge, and a quarter fits .058 gauge. This makes it easy to find out your chainsaw gauge, a very pertinent specification when buying a new chain.

• Looking for Information on the Chainsaw

Your chainsaw itself could provide a wealth of information. Often, key details are stamped on the chainsaw bar near the rear end near the point closest to the cutter. You are likely to find both the chainsaw bar length and chain size marked here.

However, remember that with use and wear, this information might fade away, rendering this approach ineffective. In such cases, manual measurements are your best bet.

• Exploring Beyond Direct Replacement

When it comes to chainsaw bars and chain replacements, going for a similar replacement should typically serve you well. It ensures compatibility and guarantees seamless performance just like the previous bar or chain.

However, results can significantly improve by exploring options beyond direct replacement. For instance, a laminated bar consisting of two steel rails sandwiched over a steel core may work better. These bars are lighter, durable and are ideal for smaller chainsaw applications.

Another excellent option is a carbide-tipped chain. Compared to standard steel chains, carbide chains stay sharp for longer, cutting down on frequent sharpening and ensuring the chainsaw is always ready for use.

All in all, aligning your chainsaw bar and chain with your needs and the tool’s capabilities enhances performance and ensures safety. The selections should reflect adequately on the saw’s horsepower, the nature of tasks you intend to complete, and personal preferences for performance and maintenance.

Here is a useful link to the Oregon State University article, which talks about effective chainsaw usage and maintenance. This resource, notwithstanding its academic nature, is a great guide to understanding the role of chainsaw bar size and chain selection in overall chainsaw performance.

In conclusion, with this knowledge of chainsaw bar and chain selection, you should be better equipped to make an informed decision when the time comes for a replacement.

With the right understanding of your chainsaw’s capabilities, needs, and your tasks, it’s quite convenient and fulfilling to keep your chainsaw – a potent tool that saves time and effort, in optimal shape.
