Chainsaw Sharpener Buying Guide
Although chainsaw sharpeners almost perform the same functions, they are quite different in their anatomy. For you to get the most value out of your purchase, there are several parameters you should go by. Here is a quick guide on the essential attributes to consider when buying a chainsaw sharpener.
1. Cutter Type
A crucial attribute to consider when buying a chainsaw sharpener is the cutter type. This is the part of the chain that performs the cutting action. Chainsaws often come with chisel, round, or semi-chisel teeth, and the shape determines the type of sharpener to use.
- Round Cutter. This type of cutter is the easiest to file and most versatile in terms of cutting action. Round teeth endure dust better compared to chisel teeth and are easy to sharpen with a manual file.
- Semi-chisel cutter. This cutter is halfway between chisel and round. It is more aggressive than round cutter but more delicate than the chisel cutter. These cutters could be filed with manual sharpeners designed for round teeth, tolerate dust and dirt better, and stay sharp for longer.
- Chisel cutter. This cutter is the most aggressive of all and shouldn’t be used by inexperienced chainsaw users. Often used for industrial applications, this chain needs a specific sharpener. The teeth are also susceptible to dirt and dust, so they need frequent sharpening and constant maintenance.
2. Chainsaw File Size
Another crucial attribute to consider when buying a chainsaw sharpener is its file size. The file size is usually expressed in millimeters or inches and typically determines whether a sharpener is compatible with a saw. Chainsaw chains usually have different file types, but the most common ones are:
- 0.404-inch (5.5 mm)
- 3/8-inch (5.2 mm)
- 0.325-inch (4.8 mm)
- ¼-inch (4 mm)
The size expressed in millimeters often refers to the round file’s diameter while its equivalent in inches represents the size of chain pitch. Some sharpener models can be adjusted to be compatible with all the pitches above, whereas others only work with one pitch.
Specialty sharpeners are only compatible with a single chain pitch and are best suited for personal use. Industrial or commercial users working with different chainsaws could benefit from an adjustable sharpener capable of handling all their tools.
3. The Chainsaw Gauge
The chainsaw gauge is another important parameter to go by when buying a sharpener. The chainsaw gauge checks the cutter’s length, and there are four gauge types:
Despite the gauge size, it isn’t advisable to file below 0.025 inches. However, the depth of your gauge is crucial since it determines the extent at which your chainsaw cuts. You shouldn’t file the gauge along its length since it shortens its service life. While filing the gauge, be sure to sharpen evenly all through otherwise your chain will vibrate and result in rough cuts.
4. Type of Sharpeners
Chainsaw sharpeners come in different sizes and styles. Some universal models are ideal for use with all chains while others are chain-specific. Basically, you’ll typically have the option to choose between electric and manual models. Although manual sharpeners seem more old-school, they still have advantages that have kept them on the chainsaw sharpener market. Manual sharpeners are then divided into handheld and bar-mounted sharpeners.
- Handheld sharpeners. These are the most popular since they are cheap, portable, and easy to use. Most of these sharpeners are round file models with different diameters. Despite having a simple sharpening process, it could also be tiring and time-consuming. Besides, maintaining the right grinding angle is difficult with such sharpeners.
- Bar-mounted sharpeners. These are more appropriate for a shed or workshop since they require mounting on stable platforms like a wall, vise, or workbench and have adjustable settings that make them compatible with multiple chainsaws. You can easily adjust the filing depth and angle, and there’s often better control over your grinding actions.
- Electric sharpeners. Although they are more expensive than their manual counterparts, they will do most of the dirty work for you. Just feed your chain into the grinding wheels, and the sharpener does the rest. Powered by a 120V outlet, these sharpeners do not require any unique predisposition in your home circuit.
Top 3 Chainsaw Brands
Although the battle for supremacy among the top chainsaw sharpener brands; Stihl, Timberline, Oregon is fierce, you will still get value for money from any of these brands. If you talk to random users, you’ll realize that there’s almost a proportion split among those who prefer each brand. We all have our own rationale for why we prefer a specific brand over the other, but ultimately, all three brands have several professional-grade, high-quality models that perform well. So, the choice is all up to you.
While Oregon is widely regarded as the best manufacturer, Timberline and Stihl are still worthy of your time and money. Each brand will give you a superior performance to other consumer brands you’ll find on the market. All three manufacturers offer various models that appeal to just about anyone, so a quick comparison would help you better understand the perks of each brand.

Depending on the users’ needs, these sharpeners come in various designs and price categories, from a simple manual filing tool to universal sharpeners for circular saw blades and saw chains.
Many users admit that Stihl sharpeners come with a low-end torque which makes them a great choice for touch sharpening jobs. Besides producing high-quality sharpeners, Stihl products also have an excellent reputation for requiring minimal routine maintenance. When it comes to manual chainsaw sharpeners, Stihl arguably produces the best. Stihl sharpeners not only provide cutting edge performance but are also optimized in terms of their weight, strength, and durability.
Oregon is another famous brand among chainsaw enthusiasts because of its specialization in electric chainsaw sharpeners. With their grinders in your hands, you can take on any job – whether small or big. If you’re looking for power output, Oregon workhorse bench grinders are possibly the best alternative. And whether you want a model for occasional use or high-volume sharpening, there’s a tool to meet your needs. In terms of design, this brand easily wrestles down its competitors. However, if you’re working on a budget, this brand might not be the best option for you since their products are quite pricey. Oregon sharpeners are easier to buy online and have a reputation for grinding faster than Stihl.
Timberline is a superior chainsaw sharpener brand that is hailed for its extended lifespan. Most of timberline sharpeners can handle a minimum of 40+ sharpenings in a lifetime. In terms of build quality, Timberline sharpeners are superior to the other two brands and work pretty much with any chain. Chains that can be sharpened with round files are compatible with Timberline sharpeners. Besides, the convenience of portability makes this brand a bargain in addition to being a real time-saver.
Everyone’s experience differs based on their preferences and needs. Some prefer the torque and minimal maintenance of Stihl sharpeners, others prefer the great design and grinding speed of Oregon, while others prefer the durability and compatibility of Timberline. The most important thing is that each chainsaw sharpener does the job efficiently and safely.
Q1. What is the angle for sharpening a Stihl chainsaw?
Ans: Stihl chainsaws are typically filed to an angle of 30 degrees, which is usually parallel to the service mark of the filing angle. You are required to hold your sharpener so that a quarter of its diameter protrudes right above the top plate. Before you can begin sharpening, mark one cutter with some ink and after a few strokes, check how the material has been removed. A uniform surface indicates that your filing action is correct while patches of color show inappropriate sharpening.
Q2. What is the best professional chainsaw sharpener?
Ans: The Oregon 520-120 is, in our opinion, the best professional chainsaw sharpener. Besides having incredible grinding power and speed, this grinder comes with three different wheels for great versatility. It comes with a built-in work light that helps ensure that you are sharpening at the same angle and sharpness. Since it is a mounted grinder, we recommend it to those who work from a workshop or studio.
Q3. How tight should a chainsaw chain be?
Ans: Professionals often refer to “snap tight” as the right amount of tension on your chainsaw. This basically means that you should easily pull the chain up until the drive links are partly exposed but not completely free of the cutter’s guide bar. If your chain’s tension is just right, it snaps back right into place when you pull on it.
Q4. How do you tighten the chain on a chainsaw?
Ans: To tighten your chain, you need to locate the tension adjustment points, which include the front and side cover of the chainsaw. Once found, turn the adjustment screw counterclockwise to loosen and clockwise to tighten. As you increase the chain tension, be sure to check the gap between the slack chain and the under-side of the saw’s guide bar. The chain on your chainsaw is correctly tensioned once the drive links have completely rested into the guide bar’s grove. Over tightening the chain could cause it to break.
Q5. Is it hard to sharpen a chainsaw?
Ans: No, it’s not. With the right tools and information, it can be a breeze. First, you will need to pick your preferred chainsaw sharpener, ensure you’re using the right size file, and file at an angle. If you’re using a manual sharpener, you need to apply even pressure for the best results.
Q6. Why does my chainsaw cut crooked?
Ans: Your chainsaw will cut crooked if the teeth on one side are more worn than the other. Since many people find one side of their chainsaw easier to sharpen than the other, it implies that one side will often be sharp while the other is dull. As a result, the chainsaw travels in the direction of the sharp teeth, resulting in crooked cuts. Sharpening the flat side could fix this problem.
