How to Sharpen Table Saw Blades?

To get your table saw blades working in top performance without the need for replacing them, here’s what to do:

What You Will Need

Before You Begin

Sharpening table saw blade

Step 1: Mounting the Diamond Blade

Remove the blade that was originally on your table saw and replace it with the diamond blade. Use the blade switch to insert and hold the diamond blade in position.  If your table saw doesn’t have this option, tighten the diamond blade in place with the nut.

Step 2: Start with the Teeth

If your blade’s teeth are all tapered in one direction, you won’t need to be turning it over for each pass as you would if it had a different pattern. Mark the tooth you start with using tape or a marker then begin until you reach it again.

Once you have a clear-cut idea of how and where to start, you can switch on the blade.

Step 3: Down to Business

Keep your fingers away from the way of the active blade, carefully touch each inner edge of the tooth to it for no more than 2-3 seconds, and move on to the next. Continue this pattern until you reach the marked end tooth.

You should now be looking at a fully sharpened blade.

Step 4: Reap the Rewards

After you’ve switched off the sharpening blade, take a small and slightly damp towel to wipe off any excess metal particles from the edge of your newly sharpened blade. Then reattach it to the table saw and try it out on a piece of lumber.

A well-sharpened blade should give no resistance, noise, or unsteadiness while it’s rotating. If you notice no change and the motor is overloading, then the blade is not sharp enough. In this case, you should repeat steps 1 to 3 again.

Conclusion

How to sharpen table saw blades is an important part of learning how to use a table saw safely. Hopefully, the steps are clear and are etched into your mind well; now, all that’s left to do is try it out yourself.
