No matter how potent is your circular saw, it is useless without a sharp blade. If you are a DIYer who uses circular saw often, you’ll undoubtedly agree. A blunt circular saw blade only provides a rougher finish. This is not what you expect from a power tool, right?

Changing circular saw blades is not happening always due to its high price. But, you can save this expense by sharpening your circular saw blade by yourself. It’s not tough at all. We will tell you how to sharpen circular saw blades.

Tools Needed.


How to Sharpen Circular Saw Blades?

Before we tell you how to do this, inspect every single part of your circular saw blade. If the saw blade is steel-toothed, you’ll need a regular file. Else if it is carbide-tipped, then you’ll need a diamond file. Follow these easy-to-follow steps.

Step 1: Take Out the Blade.

If you have newer models, you’ll see there is a release switch in the circular saw. Press the button to remove the blade carefully. Or else, for older models, use a wrench to loosen the bolts. Now put the saw blade down on a table.

Step 2: Preparation.

Before you sharpen the blade, let’s make the job easier. Use a soft brush and apply Vaseline over the saw blade and teeth. Leave it for half an hour, and it will help break down the resin in the teeth.

Step 3: Secure the Blade.

Now your blade is ready to be sharpened. Secure the saw blade using the clamp in a vertical position; make sure the teeth are facing you. Do not over-tighten the clamp as it may bend the saw blade.

After that, mark on the tooth at any point using the marker. Thus you will know when you covered all the way around.

Step 4: Start Filling.

So your blade’s teeth are aligned in the same direction concerning the saw blade. You may notice there has a bevel on every two-blade points. Now hold your diamond file at 20o angle regarding the saw bevel.

Make four smooth strokes up and down beside the bevel of the first tip. Inspect the first tooth if it has a sharp edge or not. If not, then make a few more strokes and see. Otherwise, move to the next tooth.

If the next teeth are beveled, then skip this one and move to the next. Sharpen all the following blades using the required number of strokes. Do the same until you are satisfied.

Now, turn the blade when you are done with one side. Repeat the same process for all the saw blades on this side. Stop filling once you have reached the starting point.

Step 5- Remove and Re-Install the Blade.

You may have to sharp this way two to three times. Once you are done, release the blade from the clamp and install the saw blade back in the circular saw.
