How to Sharpen Table Saw Blades

A table saw is a woodworking tool that is used to make accurate cuts on different types of wood. However, with repeated use, the blades can become dull and reduce the accuracy and quality of cuts. Therefore, it is important to learn how to sharpen table saw blades to keep them in good condition.

In this post, we will be discussing the steps for sharpening table saw blades, including the tools required, safety measures, and tips for achieving a perfect sharpened blade.

Step 1: Safety First

Before embarking on sharpening your table saw blade, it is essential to observe some safety measures, like disconnecting the power supply of the tool, and wearing gloves, eye protection, and earplugs. You don’t want to expose yourself to injuries due to blade scratches or flying metal particles.

Step 2: Clean the Blade

Take off the blade from the table saw and use a cleaning brush to get rid of any accumulated sawdust, debris, or resin on the blade. Then, soak the blade in a solution of acetone or paint thinner for about fifteen minutes. This step helps to remove the stubborn grime. Use a rag to dry it.

Step 3: Remove Dulls

Identify the dull areas on the blade and mark them with a marker. You can use a metal diamond file or a coarse sharpening stone to remove the dulls. Place the blade in a vice so that it is firm and stable. Work in a back and forth motion with light pressure on the blade edges. Begin with the largest dull area, maintaining the same angle and pressure as you move to the others. Then, switch to finer grit in your sharpening process and repeat the back and forth motion on the surfaces of the blade to remove any burrs.

Step 4: Balance the Blade

After sharpening the blade, you need to balance it. Use a blade balancer or a nail to hang the blade from the center hole. If it becomes unbalanced and moves to a particular side, file it lightly on the opposite end to reduce the weight until it’s perfectly balanced.

Step 5: Reinstall the Blade

Once the blade is balanced, it is now safe to reinstall it into the table saw. Secure the blade with bolts and ensure that it’s in perfect alignment with the saw’s fence. Check the blade’s tension and adjust it based on the manufacturer’s recommendations.


Having a sharp table saw blade is essential for maintaining precise and smooth cuts. By following the above steps, you can keep your blade in top-notch condition and ensure that it serves you for a long time. Remember to observe safety measures throughout the sharpening process.

Always handle the blade with care, and keep it away from children’s reach. Stay safe and enjoy woodworking!
