3. Prepare the saw blade

A dull saw blade will be the main character in this stage.

Remove the blades and continue with another job

You should completely remove the table saw blade from the table saw. Some people think that leaving the table saw blade in the table saw is easier to do.

However, it is a big mistake. When the saw blade is on the saw, it will cause difficulties in the grinding process. 

Because they cannot fix themselves in one position at all. It will move continuously and reduce the accuracy when grinding the saw teeth.

On the other hand, dull saw blades are not sharp, but they can still cut your hand when they lose control.

You should seek safety in the first place. Please remove them and continue with another job.

4. Fixed diamond blade

We made the saw blade dull, and replaced it with a diamond blade. You can use the blade switch or the nut to fix the diamond blade.

In case you use a nut to tighten the diamond blade, you should do so carefully. Do not squeeze them too tightly, and it may warp the blade.

 On the contrary, a loose nut will not help you fix the diamond blade. You should tighten the nut to a moderate degree.

5. Align the teeth

To sharpen the saw blades completely, you need to sharpen all the teeth they have. However, there are many jagged edges and the enthusiasm to work can make you forget where to start.

The best way to fix it is to mark the cog where you started. Marking with a short piece of tape or a splash of pastel can be a good solution.

Sawtooth also has different types. If they all point in the same direction, you can grind each tooth at a time. In contrast to the more complicated aliasing, you should do it more than once.

6. Fill the teeth

This step is the most crucial. You connect the power of the saw, turn it on. Once the diamond blade has rotated steadily, bring the tooth marked on the saw blade closer to the diamond blade.

Carefully touch the tooth blade to the diamond blade. Make sure the edge of the tooth blade touches the diamond blade.

Fill the teeth 

The fast speed and hardness of the diamond blade will help the blades become sharper.

After grinding, continue with another blade. Repeat the process until the last tooth blade.

7. Remove the diamond blade

After finishing sharpening the saw blade, remove the diamond blade. Use a clean cloth or brush to remove any remaining dirt on the diamond blade.

Cleaning it before storing it away will ensure it lasts longer.

8. Reinstall the saw blade

We will check the sharpness of the saw blades right after sharpening them. Install the finished table saw blade into the table saw. Close the lock switch or tighten the nuts tighter to secure them. Then turn on the button.

Start cutting with any piece of wood. If you see a smooth cut, the cut is easy. You have sharpened the table saw blade properly. You should carefully apply some oil to the table saw blade to maintain it.
