Tips for Sharpening Chainsaw Blades

Can chainsaw blades be sharpenedIf you have been having problems with your chain saw then it’s probably time to sharpen the blade. Have you noticed your chainsaw blade buckling as it cuts through wood? Or does it leave burn marks? If the answer to either of these questions is yes then your blade needs sharpening. It can be very slow and dangerous using a chainsaw with a dull blade. Many people feel that they are unable to sharpen their own chainsaw blades and would rather pay someone to do the job for them. However sharpening the blade is actually much quicker and easier then you previously anticipated. Follow these simple steps to get your chainsaw back into good working order.


For this task you will need a pair of gloves to protect your hands from the blade. You will also need a filing kit. Special filing kits that have been designed especially for chainsaws are available from most garden centres or hard ware shops. They contain a guide, depth gauge tool and files. You can use a flat or a round file to sharpen the blade. It’s not advisable to use a rat tail file for sharpening as this can ruin your chainsaws blades.

Follow these simple steps

  1. It’s important to make sure that the chainsaw brake is on to avoid any accidents. Once you are happy that your chainsaw is safely turned off, lightly clamp the bar in a vice so that you are able to work on the blade.
  2. Your filing kit should contain a guide which you can place between the rivets of the chain. The guide will have you to file in the right direction and will also stop you from filing too deeply.
  3. Place the file on the guide and gentle move back and forwards two or three times. You will notice that the face of the cutter turns a silver colour. Continue sharpening each cutter in this way.
  4. After you have sharpened a couple of the cutters, you will need to release the chainsaw from the vice and move the chain round so that you are able to sharpen the other side. Do this until each cutter looks clean and sharp.
  5. To make sure that the cutters can reach the wood, use a depth gauge tool to adjust the height of the depth gauges on the chain.

To ensure that your chainsaw is working to the best of its ability it is important to sharpen the blade regularly. This is a simple task which can take as little as ten minutes. It’s a good idea to get in the habit of sharpening the blade every time you refill your chainsaw with fuel, then it will always be sharp when you use it. Keep the chainsaw blades out of the dirt when cutting as this will make it dull more quickly.

If you want an even easier way to keep your chainsaw blades sharp, you can use a rotary tool. To do this place the grinding wheel on the cutter. Turn it on and grind the cutter to the count of four. Make sure that you always use safety goggles when using power tools.
