How to Sharpen A Circular Saw Blade By Hand

Easiest Steps to Follow

Here, I will detail the entire process of sharpening a circular saw blade step-by-step.

Step 1

At first, you want to make sure that the battery is disconnected or at least the device is unplugged. Otherwise, it may lead to an accident which can be harmful for both you and the device.

Step 2

Majority of the devices have a wrench built into them to help you unfasten the bolts securing the blade. You shouldn’t have much difficulties in unfastening the bolts.

Step 3

After removing the blade, you need to take a grease pencil and mark the blade at the point where you are going to start. You can then secure it in a vice. Make sure that the vice is clamping down on the face and that you don’t have any of the teeth inside.

Step 4

Use a file like the triangular shaped ones for sharpening. The teeth are angled at about 20 degrees. That’s why you need to begin with the marked one.

Step 5

Match the angle and run the file in zig-zag fashion 4 times. Next, skip a tooth. Repeat the process and proceed all the way around the blade.

Step 6

When you are ready to do the other ones, pick the one next to the mark up. So, by turning the blade around, you can keep the same angle and the same pressure.  “Step 2” will be repeated again here. After that, just lightly go over the top.

Step 7

Now, you have to put a little bit of pressure because most of these blades are using carbide tip blades which are very strong. However, they stay sharp for a long time.

Step 8

Do about 4 strokes on the side and a few strokes on the top. This will sharpen the points and give you a real sharp blade.
