How to Sharpen Table Saw Blades?

If you’ve been working with your table saw blades for a while you know that eventually they’ll wear down and start to dull. Many people go out and buy a new blade before you continue with your work – but you actually don’t need to do this. You can fix your table saw blades up – good as new – without having to come too far out of your pocket.

To sharpen your table saw blades, all you need to do is invest in a diamond blade and keep some safety precautions in mind. The first thing you’re going to need to do is change out your circular blade for the diamond saw blade. Take your time when you do this and be sure that your table saw is unplugged and turned off before you get started. Click here to read our complete reviews on the top table saws.

Once you’ve switched out the circular blade for the diamond blade, put on your safety gear. You’re going to need to get a sturdy pair of safety goggles and a pair of earphones that will reduce the noise that will be created by the machine. You should also invest in a sturdy pair of gloves that will help to keep your hands safe while you work with the metal. Some people even go as far as to invest in respirators when they sharpen their table saw blades.

This isn’t entirely necessary, but if you want to take the added precaution you are free to do so. You’ll also need a jig to work with that will help to prop up the blade while you’re working and keep it off the table top. If you don’t have a jig you can substitute it with a sturdy material like drywall, but using a jig will be much easier.

Once you’ve got your setup, take the circular blade that needs to be sharpened and put it up next to your diamond blade. You’ll be sharpening the inside of the tooth (where all the carbide is) and just touching it up against the diamond blade briefly. That will help to get it nice and sharp again so you’ll be able to work quickly and efficiently again. Practice this motion a few times so you can get the hang of it.

Next, turn on the table saw and push the first tooth up against the diamond blade. Touch it briefly and then pull back and put the next tooth up to the diamond blade. Continue to do this until all the blades on your table saw blade are sharpened. That’s it! You’ve managed to save the blade you’re working with and learn a technique that can help you in the future.

Keep in mind that this process won’t work for all blades that you can buy. If the table saw is older and has a curve to the blade instead of the straight edge you tend to see on the modern equivalents, you won’t be able to sharpen it using this method.

You’ll also need to make sure that the tooth has enough carbide on the blade to sharpen it – if it’s been sharpened too much or worn down to the point of not having enough carbide left on the tooth you won’t be able to sharpen the blade enough to work well with.
