How To Sharpen A Mitre Saw Blade

If you work with wood or other materials, a mitre saw is an essential tool to have in order to make precision cuts. However, over time the saw blade can become dull, and it’s important to know how to sharpen it to ensure that it continues to work effectively. In this article, we’ll give you an overview of the steps needed to sharpen a mitre saw blade.

How a Mitre Saw Blade Works

Before we dive into the steps to sharpen a mitre saw blade, it’s important to understand how the blade works. A mitre saw blade is a circular saw blade with teeth on its outer edge.

  • Mitre saw blade
  • Socket wrench
  • Soft-bristle brush
  • Blade sharpening file
  • Safety glasses
  • Work gloves

Steps To Sharpen A Mitre Saw Blade

Steps To Sharpen A Mitre Saw Blade

Turn off the Power: The first step in sharpening a mitre saw blade is to turn off the power to the saw. This will ensure that there is no accidental movement of the blade during the sharpening process.

Remove the Blade from the Saw: Use the socket wrench to loosen and remove the blade from the saw. Follow the manufacturer’s instructions for removing the blade.

Clean the Blade: Use a soft-bristle brush to remove any debris or sawdust from the blade’s teeth.

Inspect the Blade: Inspect the blade for any cracks or damage. If you find any damage, it’s best to replace the blade rather than trying to sharpen it.

Secure the Blade: Secure the blade in a vice, with the teeth facing up.

Start Sharpening: Use the blade sharpening file to sharpen each tooth on the blade. Hold the file at a 45-degree angle to the tooth and push it away from you in one smooth motion. Repeat this process for each tooth on the blade.

Alternate Teeth: After you’ve sharpened every other tooth, rotate the blade so that the unsharpened teeth are facing up. Continue sharpening in the same manner.

Balance the Sharpness: Once you’ve sharpened all of the teeth on the blade, use a balance tool to ensure that the blade is evenly sharpened on both sides.

Reinstall the Blade: Follow the manufacturer’s instructions to reinstall the blade on the saw.

Test the Blade: Turn on the saw and test the blade to ensure that it’s cutting smoothly and accurately.


  • Be careful when sharpening the teeth on the blade, as the teeth are very sharp.
  • Use a blade sharpening file that is the correct size for the blade teeth.
  • Wear protective gear, such as safety glasses, work gloves, and a dust mask, when sharpening the blade.
