How to change a table saw blade

For carpenters and DIYers, replacing and changing a table saw blade is a basic task that may need to be done multiple times on multiple projects. Table saws are used on construction job sites and in home workspaces and are one of the fundamental tools for many job projects. Occasionally the blades need to be changed because they have become dull and old. However, table saw blades can also be changed according to the materials being cut for the specific project at hand. Types of table saw blades include rip blades, smooth cut blades, and shear blades, just to name a few.

Necessary materials

• New table saw blade
• Screwdriver
• Allen or hex key
• Small block of wood


Step 1 – Turn off the power

By locating the power switch on the table saw, turn the saw off. Also, for added safety, unplug the saw from the wall outlet to completely disconnect power to the saw. Allow the saw to settle for a moment to ensure all power is drained from the machine.

Step 2 – Remove the plate

blade Locate the blade plate on the table saw. With most table saw models, the blade plate is the metal plate that sits on the top surface of the table saw.

Most blade plates are secured with at least two screws, one at the front and one at the back, so loosen and remove these screws to remove the plate. Set the plate aside out of the way.

Step 3 – Remove the blade

Move the blade so that it is in the highest position. For safety, place a small block of wood against the blade to prevent the blade from turning accidentally.

Locate and remove the nut and washer from the blade by turning the nut counterclockwise (towards you) with a wrench.

Remove the blade and set aside while you work.

Step 4: install the new blade

With the blade teeth facing the front of the table saw, place the blade into the blade housing.

Put the washer and nut in place and secure the blade in place by tightening the nut with a wrench by turning it clockwise (away from you). Hold the blade securely with the small block of wood.

Step 5 – Reinstall the blade plate

Using a screwdriver, reinstall the blade plate by tightening the screws that secure the plate to the top of the table saw.

Step 6 – Reconnect the power.

Plug the saw into the outlet to reconnect the power. Turn on the saw and run the blade to determine if the blade is properly installed and working properly.

Once you know how to replace a table saw blade, it will become a routine activity that requires very little advance planning or special effort. In the course of a project, you may find that you need to change a blade multiple times as you work with different materials or need to make different types of cuts to complete your construction or home improvement project.
