How To Sharpen A Circular Saw Blade With A File | Tips And Tricks

Do you have a circular saw blade that needs sharpening? I was in the same boat not too long ago. I needed to sharpen my circular saw blade but didn’t know how to do it. So I did some research and found a method that worked well for me. And now I’m going to share that information with you.

In general, to sharpen the blade first, identify the teeth on the blade that are damaged or dull. Then, using a flat-file, sharpen the teeth by filling in a back and forth motion.

By the end of this article, you will know how to sharpen your circular saw blade with a file like a pro – using nothing more than a simple file.

How To Sharpen A Circular Saw Blade With A File Step By Step Guide:

Here are some steps to do this easily

Step:1

Wipe the blade free of any debris, especially if it is a woodworking blade with metal shavings stuck to the teeth. The file will work better and not gouge the blade if you start with a clean one.

Step:2

Lay the file at a shallow angle and push along each tooth in one direction only. Be sure to return back to your starting point after you finish with each tooth so that the opposite side of the blade is not sharpened twice. This will ensure that both sides remain equally dull and keep the blade balanced for safe operation.

Step:3

Rotate the blade as you go over each tooth. This will ensure that you can cover all areas of each side of the saw blade evenly for even sharpening. If you rotate the blade with your hands, use caution not to drop or cut yourself on the file or saw blade!

Step:4

Repeat steps 2 and 3 until you have sharpened the entire length of each side.

Step:5

If you are using a woodworking blade with metal shavings stuck to the teeth, clean the blades off before continuing with step 2. The file can also be used to remove residual debris from the saw blade after cleaning it.

Step:6

Inspect your work if there are any rough or jagged areas on the blade, apply a little more pressure and sharpen it again. The teeth should be evenly sharpened and appear as a gentle curve from the top to the bottom of the file.

Step:7

Put everything away and get back to work!
