How to Choose Electric Chainsaw Sharpener?

Sharpening a chainsaw

With so many tools and machines out there claiming to sharpen your chainsaw back to its full performance potential, it can be a little tricky deciding which one is right for you.

So, check out this handy buyer’s guide and FAQ section to point you in the right direction. Here’s what you should be looking out for.

Chainsaw Use

Perhaps the most important factor to consider is how often do you actually use a chainsaw?

Understanding this will give you a clear indication of the type of chainsaw sharpener you’re going to need – or if you need an electric one at all.

For weekend DIYers, hobbyists, or casual homeowner use, it might be worth looking at manual sharpeners instead.

They’re significantly cheaper than most electric versions, and much more suitable if you’re rarely using your machine.

For professionals or anyone who is regularly putting their chainsaw to good use, then electric sharpeners are the way to go.

It’s then up to you to decide the type.

Static or Portable

Typically, a chainsaw sharpener can either be a portable device you can bring to the job site, or – perhaps more commonly – a unit that you can mount to a bench or a wall in your workshop.

Say you’ve established that you’re using a chainsaw regularly, then I would suggest a dedicated workbench mounted sharpener is preferable – particularly if you have a collection of chains to work on as this will save you a lot of time and effort in the long run.

If you’re short on space, look for a sharpener that can be mounted on the wall. Even so, you’ll find that the ability to mount the unit around eye level will eliminate the fatigue of stooping over to sharpen multiple chains.

Having said that, also carrying a portable electric chainsaw sharpener isn’t a bad idea – especially on longer, larger jobs.

The ability to quickly sharpen a chain on site will keep your saw operating at maximum performance, which will increase your efficiency and safety at the same time.


Consider the voltage of the electric chainsaw sharpener that you’re mulling over. It’s not rocket science here and I won’t labor the point – the higher that number, the more powerful the motor and the higher the RPM.

And the higher the RPM, the more efficient the grinder will be.

Gauge and Pitch

When it comes to saw chains, it’s not one size fits all. There are multiple variations to consider, and before purchasing a chainsaw sharpener, you should ensure that it is compatible with the chains you’re using.

For this, you need to know the gauge and pitch of the chain.

The gauge figure represents the thickness of the drive links. If you’re having trouble locating this number you can use a pair of calipers and measure it yourself.

The pitch figure represents the distance between these drive links. You’ll find that most chainsaw sharpeners cater for the common pitches, 1/4″, .325″, 3/8″, 3/8″ low-profile, and .404″.

To find the pitch of your chainsaw chain, simply measure the distance between three rivets on the chain and divide by two.

For replacing chainsaw chains, you’ll also need to know the number of drive links as the third most important figure in saw chain maintenance and management.

Accessories/Extra Features

Chainsaw sharpeners might come with some additional features to help make life easy for you.

Extra grinding wheels to accommodate different pitch sizes, dressing stones to remove debris or residue from the wheel, an adjustable grinding depth so you don’t cut into the metal too much, or perhaps an LED light to help you see what you’re working on. And more.

It’s up to you to decide what’s important for your needs when checking the specifications of an electric chainsaw sharpener.


Sharpeners vary from around $20 to over $400 – sometimes more. Again, I would urge you to choose a product that suits the job – rather than your budget.

There’s no need to break the bank if you’re only using a chainsaw once in a blue moon.


How to Sharpen a Chainsaw Chain With an Electric Sharpener

At first, chainsaw sharpeners might look like they’re a challenge to use – and being honest, it might take you a bit of practice to get right. There’s a lot to consider before you simply bring down that grinding wheel onto the chain.

You need to check what angle your particular blade should be sharpened at, and adjust your sharpener accordingly.

I could write a full page guide on the tips and tricks for sharpening a chainsaw using an electric sharpener, but you should check out the excellent video below for a visual reference guide instead.

It includes both hand sharpening and electric sharpening. But pay particular attention to where they’ve mounted their electric unit (and also note I’ve covered that particular model in the review above).

And just for good measure, the video below is also packed full of useful chainsaw sharpening information – just in case you want a different perspective.

Why should you sharpen a chainsaw?

Chainsaws are probably the most lethal power tool you can own – they’re extremely dangerous from the get-go. But if you’ve got a dull chainsaw chain, then you can double or even triple just how dangerous they can be.

Like all poorly sharpened tools, you’re risking serious injury when you try to use a blunt instrument on whatever project you’re working on.

One of the most common chainsaw related injuries is when the tool kicks back – which will happen considerably more often if the chain teeth haven’t been adequately maintained.

Aside from this, the power and performance of a chainsaw is seriously affected and will take a nosedive if you’re trying to run a dull machine. As well as risking serious injury – failure to keep a saw chain sharp guarantees you’re creating a lot more work for yourself.

Furthermore, you’re increasing the likelihood that you’ll permanently damage the chainsaw itself. But don’t take my word for it, check out the video below.

How often should you sharpen a chainsaw?

A rule of thumb is that you should sharpen a chainsaw every five to six hours of use – or after any particularly tough cutting jobs.

However, if you hit dirt during the course of your project, then you need to stop and sharpen immediately.

Likewise, if you feel the chainsaw is not performing to its regular standard, then sharpening the chain might be a good troubleshooting option.

Why does my chainsaw get dull so fast?

This could be for any number of reasons.

Perhaps the first one should be to make sure you actually have the chain on correctly. An improperly fitted chain is one of the most common reasons your machine doesn’t work as well as it should.

Believe it or not, some inexperienced users complain of a dull chainsaw when the blade has been put on backwards.

Next, check the guide bar. It should be perfectly straight and flat with no damage on both the top and sides. If there is a twist, your chain might be an incorrect gauge.

Cutting dirty wood can cause a lot of issues as debris can quickly nullify a chain’s performance.

Likewise, hitting earth or dirt is a super-fast way to dull a chainsaw, so be careful where and how you’re cutting.

Finally, improper sharpening techniques could be at fault and you might start the job thinking your ‘saw is sharper than it actually is. Check the videos in this review for more advice on how to properly sharpen your chain.

How often should you replace chainsaw chains?

With sensible and correct use, you should be able to get a very long life out of a single chainsaw chain. Perhaps five years or more.

But they don’t last forever, and as a portion of the metal is worn away every time you sharpen, there’s only so many times you can do this with it remaining effective and you should consider replacing them eventually.

However, exactly when this is can be confusing, and it will depend on how often you’re using the tool and the type of work it’s being used for.

Check out the video below for some great visual advice on how long a chainsaw chain will last, and how you can tell that it needs to be replaced.

How do I know if my chainsaw needs sharpening?

There are a couple of simple tricks you can utilize to know almost instantly that your chain needs sharpening.

The most obvious one is when you start to feel heavy resistance. If you feel you’re having to force the saw through the wood, then it’s a sure-fire indication that the blades are dull.

Second, check the waste material that has been produced during every cut. If you’re getting wood chips, then the chainsaw chain is sharp and good to go.

If you’re getting powder or fine sawdust, then it’s time to give your chain a sharpen.

Regularly check your chain to make sure there’s no damage or imperfections, as you can often tell by sight when it’s time to sharpen – or to replace.

Do I need to wear safety equipment when sharpening a chainsaw chain?

It’s highly advisable.

Protective eye goggles are especially encouraged when using such machines, as sparks can be unpredictable and shoot anywhere.

There’s always a risk that slivers of metal could also break off – and nobody wants that debris flying into one’s face.

I would always suggest donning a pair of protective gloves, too, but It’s unlikely you’ll need ear protection unless you’re actually operating your chainsaw.


It’s very important to keep chainsaws sharp, so they can run at optimum performance and as safely as possible.

Filing the teeth by hand can take time and effort, but electric chainsaw sharpeners will do it in no time.

If I were to choose a product from this review, I’d have to go with one of the Oregon models. Sure, they might be expensive, but they’re easily the best tools for the job and highly recommended if you’re regularly working with chainsaws.

Let me know which sharpener you would choose and why.

Stay safe and stay sharp out there, people!
