8 Best Chainsaw Sharpeners – Review

1. Oregon 520-120 Bench Saw Chain Grinder

Let’s start off with a look at the Oregon 520-120 Bench Saw Chain Grinder. If you have multiple chainsaws and chains to keep in top working condition, this is the machine to help you do it. Designed to be bench mounted on a work table or tool bench, the Oregon 520-120 lets you handle every stage of chain sharpening and maintenance in a single workstation.

It can handle sharpening any chainsaw blade, including ¼-inch, ⅜-inch low profile, and 0.325-inch, full profile ⅜-inch, and .404-inch pitch chain as well. The integrated chain vice is self-centering, allowing you to set your dull chain in place, lock it down, and start putting fresh edges on the teeth in seconds. The 520-120 also has a built in dressing brick for smoothing out minor sharpening jobs and finishing extensive ones, and a quick-check grinding template to help you evaluate how much sharpening is needed for your chain.

You also get three grinding wheels that allow you to sharpen any type of chainsaw blade. Put the right grinder wheel on, dial in the correct settings using the locking top plate and down angle control settings and you’re ready to go. This saw chain grinder is built for high volume sharpening work, and saves you time and money both in the field and around the shop. Tree surgeons, independent timber workers, and major logging operations stand to benefit most from this fast and effective chainsaw sharpener.

What we liked:

  • All-in-one chainsaw sharpener that can be used to sharpen almost any kind of chain
  • Locking chain vice holds your chain secure while you sharpen
  • Grinding angle templates make fast, accurate sharpening possible

What we didn’t like:

  • Not a cost effective option for those who don’t maintain multiple chainsaws
  • Requires 120V AC to run, so it can’t be used in the field unless it is bench mounted on a truck with a power inverter
  • Steep learning curve for those not familiar with how to sharpen chainsaw blades

2. CO-Z Electric Chainsaw Sharpener

Next up we have the CO-Z Electric Chainsaw Sharpener, another bench mount sharpener built to handle high volume chainsaw maintenance. CO-Z built a lot of customization into their sharpener, and it’s among the most versatile chainsaw sharpeners in its class. The grinding angle of the CO-Z ranges from 0-30 degrees with the motor capable of a 0-70 degree angle range. Regardless of what type of chain you need to sharpen, the CO-Z can handle the job.

To sharpen the blades on a saw chain, just lay the chain across the vice with the blades facing up and lock it into place. Turn the guide plate adjustment knob to set up the correct sharpening angle, fire up the machine and start putting a fresh edge on the chain blades. The operation process is simplified enough that anyone can learn to sharpen saw chains quickly and safely with a minimal amount of training and practice.

Additionally, the CO-Z has a built in work light so you can inspect your handiwork during the sharpening process. There is also a grinding wheel enclosure that slides into place as you bring the wheel down to the blade, sheltering the user from flying filings and sparks that are thrown during the sharpening process.

The wheel guard also keeps loose clothing or other objects from becoming caught in the wheel during operation, making this sharpener much safer to operate. There are also two grinding wheels included, and the sharpener can easily be configured to handle just about any blade type on most commercially available and industrial grade chainsaws. The CO-Z Chainsaw Sharpener is perfect for busy timber and trimming operations that need to keep multiple saws sharp on a regular basis, or individuals that want to be able to put a fresh edge on the saw chain teeth with just a few minutes work.

What we liked:

  • Quickly and efficiently sharpens any type of saw chain blades
  • Integrated worklight makes it easier to inspect your work as you go
  • Sliding grinder guard protects user from flying filings and sparks and prevents outside objects from snagging or catching on the grinding wheel during operation

What we didn’t like:

  • Built to be bench mounted in a workshop rather than used in the field
  • Grinding wheel guard must be cleaned out regularly since it traps a lot of filings
  • No built-in grinding templates, so you must manually configure your grinding angle for the type of chain you are sharpening

This compact little chainsaw sharpener can help you put a fresh edge on those saw chain teeth in no time, and it can be run off of a 12-volt car or truck battery with the included terminal clamp kit.

As portable chainsaw sharpeners go, this is definitely one of the best you can buy.

7. Timberline Chainsaw Sharpener

You don’t even need to drop the chain from the saw: all you have to do is use the three position vice clamp, lock it onto the chainsaw’s main “blade”, let the chain run free, and turn the hand crank to move the teeth through the sharpener.

No additional gear is necessary, just turn the vice grips til the sharpener fits snugly, and the sharpener does the rest of the work. Every tooth on the chain is sharpened to the same exact angle and length, and all with just a few quick turns of the handle. Timberline even includes a sturdy carrying case so you can keep it clean and dry in your toolbag or hang it off your belt when you are out on the job.
