Once arranging all the equipment and materials, follow these steps to sharpen your miter saw; 

Clean the Miter Saw Blade 

Cleaning the circular saw blades before sharpening them will make the procedure smooth and safe. Use a wire bristle brush for this process and ensure that all the dirt and debris from the blade are removed. Also, use safety gloves to ensure your safety. 

Prepare a Wood Block to Clean the Blade 

When you hold it nicely in place, sharpening the miter saw blade becomes easy and safe. Prepare a wooden block with a notch and secure it to a stable surface using a vise or clamps. Fix the blade in the notch that will prevent the blade from moving during the sharpening process.

Mark the Teeth

If you don’t mark the saw blade teeth, you may file the same tooth twice or even more. It will make the teeth uneven, besides wasting time. So, use a permanent marker to mark the blade teeth to prevent unforeseen obstacles. 

File the Blade Teeth 

Use a triangle file to sharpen the saw teeth. Hold the file at an angle of 60 degrees to the tooth and make 4 to 5 strokes just in the forward direction. Keep filing the teeth unless you finish all the marks. 

Repeat the Filing 

Once done with one side, flip the blade size and secure it to the wooden block again. Repeat the filing process similarly for the other ends of the teeth. Marking the other side will also serve the same purpose, so mark each tooth using the same marker. 

Fix the Blade to the Miter Saw 

After sharpening all the teeth from both sides:

1. Remove the miter saw blade from the wooden block.
2. Reattach it to the saw carefully by following the user manual’s instructions.
3. Ensure you have secured the blade well in place to prevent any accidents.

Your miter Saw is ready for the next cutting session.
