If you own a landscaping business or like to trim your own trees, you probably have a chainsaw and chainsaw sharpener in your garden shed.
These tools help to keep that razor sharp edge needed to cut through wood cleanly and easily, prolonging the lifespan of your chainsaw and making it safer to use.
If you’re in the market for one of these tools, take a look at our reviews of the best chainsaw sharpeners on the market in 2022 to find the best product for your budget.
Why Use a Chainsaw Sharpener?
There are plenty of good reasons to invest in a chainsaw blade sharpener:
- Reduced wear – A dull chainsaw will wear out much faster than one that’s kept sharp, because the motor has to work much harder to cut through wood.
Regularly sharpening your chainsaw will help this expensive tool last longer with less maintenance.
- Reduced fuel consumption – Because the motor of a chainsaw has to work much harder when the chain is blunt, you’ll use much more fuel (whether it’s petrol or electricity) to get the job done.
- Increased safety – A blunt chain is more likely to cause an injury or property damage, and can slip out of control or break when it encounters very dense materials.
Do Chainsaw Sharpeners Really Work?
Chainsaw sharpeners work very well – but only if you buy a good quality product. They are quick and easy to use, saving you the expense of having to buy a new chain when your chainsaw gets dull, and ensuring you get a clean cut every time.
How do Chainsaw Sharpeners Work?
The chain of your chainsaw will fit into a horizontal guide on the base of the sharpener. Using a disk-shaped grinding stone (this looks like a circular saw blade with no teeth) on an adjustable head, the chain is guided through the system and filed down at the correct angle.
(Speaking of circular saws, don't miss our product review and buying guide for the best circular saws available in Australia.)
You will have to set the correct angles of the grinding head for your specific chain. The process of sharpening the chain takes just a few minutes.
Different Types of Chainsaw Sharpeners
There are two types of chainsaw sharpener, each with their pros and cons:
Manual Chainsaw Sharpeners
Manual chainsaw sharpeners work well and are affordably priced, but they are less powerful. This means that you can’t take off as much with each stroke, so it’s a bit more challenging to get the chain nice and sharp and make it last as long as possible.
Electric Chainsaw Sharpeners
Electric chainsaw sharpeners work very well and are very powerful, restoring your chain to as-new condition with very little effort. However, they are usually more expensive and you do have to be careful not to overdo your sharpening, as you can end up filing the cutters too low.
What to Look for in a Chainsaw Sharpener
- Mounting – Chainsaw sharpeners can be mounted to a wall for easy access, which is a great option if you don’t have much space in your workshop. Bench-mounted sharpeners are workable if you have a more spacious setup.
- Manual or hydraulic assist – Some of the more advanced sharpeners have a hydraulic assist feature that locks the chain in place to prevent it from moving when the grinding head makes contact.
It’s not an essential feature but it’s nice to have if you want the process to be faster. Those without it will have a manual assist feature where you tighten a knob to hold the chain in place.
- Speed – The more powerful the motor, the higher the rotations per minute (RPM) of the grinding stone. A higher RPM means the job will be completed faster, but it also means the tool is more aggressive, so it’s easier to over-file your chain.
A good benchmark is to aim for a sharpener offering around 3400 RPM.
- Pitch compatibility – Pitch refers to the distance between the cutting links on your chainsaw chain. Your sharpener will have to be able to work with the type of chain you have, and most have settings to accommodate different chain pitches.
You can usually find your chain’s pitch on the saw arm of the tool.
- Automation – Fully mechanical chainsaw sharpeners require you to unlock and feed each chain link after filing, which can be a bit of an annoying process.
Today, you can find sharpeners that fully automate this process – all you have to do is set the adjustments for your chain and let it work.
- Accessories – Today, many chainsaw sharpeners come with additional accessories that can be useful depending on how you use your chainsaw.
This includes built-in lighting, additional grinding wheels, dressing stones and wheel gauges.
Why Does My Chainsaw Get Dull So Quickly?
If you have a good quality machine with a good quality cutting chain and are finding that it’s getting dull quickly, this may be due to cutting technique (putting too steep and angle on the cutters), placing you rakers too far down, touching the ground with the tip of the saw, or cutting very tough or dirty wood.
How Many Times Can You Sharpen a Chainsaw Chain?
Generally, you can sharpen a chainsaw chain 10 times before it needs replacing.
