The Best Electric Chainsaw Sharpener Options


Types of Chainsaw Sharpeners

An electric sharpener is very different from a manual one, so it’s a good idea to understand just how a powered model works. A manual chainsaw sharpener requires more effort to accomplish the task, but it provides other benefits.


With an electric sharpener, the saw chain fits into a horizontal guide on the base, and then a disk-shaped grinding stone (resembling a circular saw blade with no teeth) is fitted into a pull-down head. The pull-down head tilts and adjusts so the grinding stone can make contact with the chain’s cutting links at just the right front angle. The guide holding the saw chain swivels to ensure the grinding wheel strikes the cutting links at the correct side angle.

At first, the most difficult part of the sharpening process may be setting all the angles correctly, but once they’re set, you can sharpen the cutting teeth on an entire saw chain in just a few minutes. As such, an electric sharpener is a go-to for those who use their chainsaw (or multiple chainsaws) frequently. Most electric chainsaw sharpeners are corded and designed for fixed installation, though handheld battery-powered units are available as well.


For those who only have a small chainsaw or who don’t use a chainsaw on a regular basis, a manual model might seem sufficient. But there’s more to manual chainsaw sharpeners than meets the eye. While they are the less expensive option, manual chainsaw sharpeners aren’t just for small tools.

Large, bar-mounted models offer high precision and, once set up, can be almost as quick and accurate as the best electric chainsaw sharpener. At the other end of the scale, a simple chainsaw file is the true budget option, though it does require a little patience to learn to use one properly.


Automatic chainsaw sharpeners (also frequently known as portable chainsaw sharpeners) sound like the ideal solution and require very little effort. They fit around the end of the chainsaw bar and place a fixed sharpening stone in contact with the chain as it runs.

Sharpening stones are curved to match the chainsaw blades, but while some adjustment is possible, it is limited. Owners of more than one chainsaw might require two different sharpeners.

What to Consider When Choosing the Best Chainsaw Sharpener

With a clear idea of how electric and manual sharpeners work, think about which style of mounting makes the most sense for your workshop. It’s important to select a chainsaw chain sharpener that has an appropriate speed and is compatible with the pitch of your chainsaw. Keep automation and digital technology in mind, as well as optional features and accessories.


Chainsaw sharpeners typically mount to either a bench or a wall. Bench-mounting works great on a large workbench with lots of space, but in small workshops, wall-mounting saves workbench real estate.

Wall mounting also permits the user to mount the tool at or just below eye level to keep from having to bend over when sharpening multiple chains. Some electric sharpeners can be mounted either way—to a bench or to a wall.

Bar-mounted sharpeners clamp around the flat metal plate that the chainsaw runs around. These are called bars, or sometimes chainsaw blades. Although manually operated, their big advantage is their portability. They can be used in the field, where it’s not possible to take a powered model.

Pitch Compatibility

Measured in inches from smallest to largest, pitch is the distance between cutting links on a chain. Chainsaw chains come in one of five pitches: 1/4-inch, 0.325-inch, full profile 3/8-inch, 3/8-inch low profile, and 0.404-inch. The most common pitch sizes are 3/8-inch and 3/8-inch low profile. Most sharpeners will accommodate at least these two pitches. Many will accommodate all five pitches.

Chainsaw chains come in various sizes. Your sharpener needs to be able to accept the chain or chains you use most frequently. This requires knowing your chain’s pitch. This number is often printed right on the saw arm of the chainsaw.

Manual vs. Hydraulic Assist

Some of the newer electric sharpeners feature hydraulic assist, which means that every time you lower the spinning grinding wheel, the hydraulic assist will lock the chain into place. That way, the cutting links won’t move when the grinding wheel makes contact.

While this is a nice feature, it’s not an absolute necessity. If the tool doesn’t have a hydraulic assist, it will most likely have a manual knob you can tighten to secure the cutting links before you lower the grinding wheel. Hydraulic assist speeds up the process.

Maximum Speed

Manufacturers measure the speed at which the grinding stone spins in rotations per minute (rpm). Rotation speeds average around 3,000 to 4,200 rpm. Though 3,400 rpm is the most common, some go considerably higher. Theoretically, a higher rpm gets the job done more quickly, but users need to be careful with sharpeners that operate at higher speeds.

While higher speeds pose no danger to the user, sharpeners with higher rpm could damage cutting links more easily. If you don’t adjust the grinding angles precisely and the spinning stone makes contact with the cutter in the wrong spot, it’s more likely to leave a gouge in the cutting link.


Depending on the level of mechanization you’d like, you can choose a basic electric sharpener that requires you to unlock and advance the chain links by hand, or you can opt for a fully automatic sharpener that does all the advancing and sharpening after you set the adjustments to match your specific chain.

Many chainsaw sharpeners adjust with the turn of a knob or handle, but a few of the newest models use digital technology to pinpoint the exact angles on the sharpener. These digital models feature LED readouts and enable you to key in the pitch of the cutting links, as well as the desired angle of the cuts.

Additional Features

Some electric chainsaw sharpeners come with additional useful options and accessories.

  • Built-in light: Possibly one of the handiest options of all, a built-in light illuminates the very spot where the grinding stone meets the cutting links, so you can clearly see if you’re grinding at the exact angle you want.
  • Grinding wheels: You can purchase stone grinding wheels separately, but you’ll often receive one or more with the purchase of a sharpener. Grinding wheels coordinate in size to the pitch of the cutting links you’re sharpening.
  • Grinding wheel gauge: This little metal or plastic bar contains notches that you can hold up to the edge of the grinding wheel to make sure the wheel is the correct width for the cutting links you’re sharpening.
  • Dressing stone: A dressing stone removes residue that may build on the grinding wheel during operation.

Best Chainsaw File

The Best Chainsaw Sharpener Option: Katzco Chainsaw Sharpener File Kit - 5/32, 3/16, 7/32

Chainsaw files are often seen as a low-cost tool for DIY users who buy an electric chainsaw but don’t use it enough to warrant the purchase of an expensive electric sharpener. However, in practiced hands, they are also great for quick resharpening away from the workshop.

With a hardwood handle plus interchangeable 5/32-inch, 3/16-inch, and 7/32-inch round files, the excellent chainsaw sharpening file kit from Katzco meets all the professional needs for field work.

Best Portable

The Best Chainsaw Sharpener Option: Oregon 541656 16-Inch PowerSharp Starter Kit

This type of portable chainsaw sharpener (sometimes called an automatic chainsaw sharpener) grinds the tops of the chainsaw teeth while the machine is still running.

Our Verdict

Frequent chainsaw users will want to consider electric sharpeners. One of the best is the Oregon 410-120 Chain Grinder, a fast and precise tool that offers a number of user-friendly features. For a manual option needed in the field, it’s hard to beat the Pferd 17300, which is beginner-friendly with automatic depth gauge adjustment.

How We Chose the Best Chainsaw Sharpeners 

Proper chainsaw sharpening tools are key when it comes to chainsaw maintenance. It’s not only important for easier tree felling, but also for woodland management. Fortunately, today’s tools make sharpening chainsaws a breeze by coming in multiple designs, being easy-to-use, and are compatible with multiple chainsaw sizes.

The above chainsaw sharpeners come in manual, automatic, and electric designs. Though the electric sharpeners provide ease of use, adjustability, and ease of use during the sharpening process, many of them require mounting which can be difficult for some users. Alternatively, automatic and manual sharpeners may require more work and strain, but are portable and easy to bring to a job site.

Many of the above picks also have adjustable pitches and angles to sharpen chainsaws of multiple sizes. Whether you are a weekend user building your firewood stack or a full-time professional, there’s a chainsaw sharpener for all needs and every budget.

Tips on Using a Chainsaw Sharpener

Proper chainsaw sharpening is very important. Not only does it make cutting easier, it’s also safer. Blunt chainsaw teeth are more likely to bind in a cut. It can be extremely difficult to remove and could ruin the chain. There’s also a much greater chance that the chain jumps off the bar, which could lead to serious injury.

How to sharpen a chainsaw is covered in a separate article, but see the main points listed just below. Whichever type of chainsaw sharpener you use, preparation and patience are key. Poor setup guarantees a poor result.

  • Wear work gloves. Parts of the chain can still hurt your hands even when it’s blunt.
  • When sharpening with the chain off of the saw, make sure the chainsaw sharpener is solidly fixed to a bench or wall. Movement will affect the accuracy of sharpening.
  • When sharpening with the chain on the saw, make sure the chain is properly tensioned to minimize movement. Also keep the saw as stable as possible by holding the bar in a vise or having some kind of backstop. It can be a challenge when working in the field. A tailgate vise or a portable workbench can be an effective solution.
  • Most chains have a “master cutter”—a tooth that’s shorter than the others. Start sharpening here, so you know you’re done when you come back around to it. If you can’t find a master, mark the chain with a piece of tape.
  • Work slowly and carefully. Even manual sharpening with a simple chainsaw file only takes a few minutes, so there’s no need to rush. If using a manual sharpener, work on the forward stroke only. Don’t rub the file back and forth.


If you have more questions about electric chainsaw sharpeners, check out this list of the most frequently asked questions.

Q: How often does a chainsaw need sharpening?

As a rule of thumb, many experts say every 10 uses, though it’s much better to judge by the feel of the chain when it’s cutting. A sharp chain cuts easily with clean shavings. A blunt one struggles to cut and produces pulp. To reduce sharpening frequency, buy the best chainsaw chain you can afford. They are worth the investment.

Q: How does an automatic chainsaw sharpener work?

Generally they clamp over the end of the chainsaw bar where the chain runs around. While the chainsaw is running, they sharpen the chainsaw teeth as they pass across the grindstone.

Q: At what angle should a chainsaw chain be sharpened?

Somewhere between 25 and 35 degrees. Some experts recommend the sharper angle for hardwoods, though Stihl, a leading maker of gas chainsaws, recommends 30 degrees for all purposes.

Q: How do you sharpen a chainsaw with an electric sharpener?

Proceed through these steps to properly sharpen your chainsaw with an electric sharpener:

  1. Determine the pitch and gauge specifications of the chainsaw blade.
  2. Make sure the sharpener is mounted securely on the workbench or wall.
  3. Set up the sharpening stone with the correct width to fit the chainsaw blade’s teeth.
  4. Place the blade in the sharpener’s holder and adjust the angle.
  5. Adjust the depth by positioning the depth stop.
  6. Lower the grinder wheel on the first tooth of the blade and maintain contact briefly.
  7. Lift the grinder and check for a shiny finish on the tooth’s inner surface.
  8. Proceed with sharpening all teeth on one side of the blade.
  9. For the other side, readjust the grinder to the negative equivalent of the chosen angle.
  10. Repeat steps 6-8.
