How To Sharpen A Chainsaw With A Grinder

Easy Steps to Follow

Get A Chainsaw Grinder

This one’s easy! Look around for a good hardware store or online store, see if they have the kind of grinder you’re looking for. And angle grinder is great for those working at home, since it can be handheld.

You could also go for one that can be fitted on to a table. This way, your grinder has more stability and you are at less of a risk. You can of course look at both types and buy the one that suits your need. Getting that grinder will be an investment for a lifetime.

Pick Out A Safe Place

Remember that as skilled as you might be with machines, it could still be a dangerous work. Choose a place away from children, maybe a shed or your garage. Be careful with how you hold and use your grinder, as the disc is extremely sharp.

If from use, the disc eventually becomes blunt, you can always put it against a stone, turn it on, and sharpen. A working sharp grinder gives you a working sharp chainsaw!

Get Ready To Sharpen!

Place your chainsaw on a table, with height and width, advantageous to your work. Make sure you have a good grip on your grinder, and locate the chains attached to it. For a fitted grinder, the chain must be taken off the saw and placed on a rail in the grinder.

This rail can be rotated, so you can get both sides of the chain. Make sure your grinder is adjusted to the right height so it can work on the right places.

Start Up That Grinder

Now that your grinder is ready to sharpen, you can start it up. Work slowly first and increase your speed as you continue. You will notice that each spike on the chain has an alternating direction.

To sharpen each spike properly, you can either grind every other spike and then rotate the chain and do the rest. Or, you could turn your handheld grinder a little for each spike and get them all in one go.


Either way, by the end, you will have a perfectly sharpened chain and if you’re careful enough, all your fingers intact too. And you can just get on with your work on the chainsaw.

Be conscious while sharpening to avoid patchy sharpening on different teeth of the chain. Maintain the perfect angle while sharpening. Grinding may take off some metal from the tooth but it will give you the best cut you want.


With a hack like this, you wouldn’t have to waste time looking for someone to sharpen it for you. Plus, you would not have to spend money every time your chainsaw goes blunt. You’ll have the machine right at home, ready to make your work much easier.
