Changing Table Saw Blade

The Table Saws are one of the most functional tools that are often used by carpenters in almost all their crafty projects. However, with time, the gradual wear and tear are quite normal. That said, it’s actually very necessary to change or replace the table saw blade when it feels like it is not working as it should.

Hence, if you are curious about it, and want to change the table saw blade in your workshop on your own, this guide can really save you a lot of your precious time and money. We will be telling you the exact and proper method so that you can change the table saw blade in the least possible time without any complications.

Steps to Follow When Changing a Table Saw Blade

1. Disconnecting the Power

Before you start the process, you must make sure the table saw is not connecting to any power source. It’s necessary to disconnect the power of the saw blade to avoid any sort of accidents. So, don’t hurry for anything and patiently confirm that the saw blade is disconnected from the power outlet.

2. Removing the Throat Plate and the Blade Guard

For the next step, you will need to remove the throat plate and the blade guard to reach the blade. Since not all the table saw machines are built with the same design, you might need to take some help from the instruction manual to remove the throat plate from your table saw machine.

3. Raise the Blade

Once you figure out and remove the throat plate and the blade guard, it’s time to deal with the blade itself. As you might know, the height of the blade can be adjusted, set to the maximum height, and raise as much as you can. It is necessary since raising the blade allows you to access the nuts and bolts conveniently.

4. Loosening the Arbor Nut

On the saw blade, you will have to locate the Arbor nut, which is generally present at the center of the blade. Loosening the blade is a bit tricky task and also requires a little bit of strength too. You will need two wrenches for loosening the arbor nut. While you hold the nut with one wrench and move it, the other wrench is needed to keep the other side of the arbor nut stationary for loosening it properly.

5. Removing the Arbor Nut

Once you properly loosen up the arbor nut, you just need to unscrew it further and take it out from the bracket. It’s one of the most important parts of the machine, so make sure to handle it properly and don’t misplace it. Also, while you unscrew the nut, make sure that it does not fall inside the machine itself, otherwise, it can create problems later on. Once the arbor nut is removed, also remove the washer and also place it securely.

6. Removing the Blade and Replacing with a New One

Since we have already removed the washer and the arbor nut, there’s nothing holding the saw blade, so you can simply take it out of the machine. Now, it’s time to place the new blade in the machine. When you put the new blade, make sure it’s placed the right way. For the correct placement, make sure the teeth of the new blade are pointing towards you, not in the other direction.

7. Replacing Arbor Nut and The Washers

If the arbor nut and the washer of the previous blade do not seem to have a good and working condition, or they do not fit the new blade properly. Then, replacing the arbor nut and washer is the next step to do. Thus, find the compatible arbor nut and washer that supports the new blade, and fix the blade in its position.

8. Replacing Throat Plate and Blade Guard

Once you have fixed the new blade in its position, place the throat plate and blade guard back and fix them.

9. Reconnect the Power Plug

Lastly, reconnect the power plug of your table saw and you can continue working on your project once again.

Useful tools to Change Table Saw Blade

  • A Regular Adjustable Wrench

In case you don’t have the right-sized pair of wrenches, there’s nothing to worry about, as any basic adjustable wrench will do the job.

  • An Open-Ended Wrench

Moreover, instead of the necessary or recommended wrenches, you replace the saw blade using the open-ended wrenches as well.

  • A Block of Wood

If you only have one wrench and you are not able to unscrew the arbor nut properly, you can use a wooden block to hold the blade in one place and stop it from moving. It will just act like a blade-lock and will stop the blade from rotating when you rotate the arbor nut.


As we mentioned earlier, a table saw is every carpenter’s most useful tool, which is used in almost every project. However, the project will only finish in time when all of the tools are in healthy condition. An old table saw blade usually cuts slowly and unevenly, which is not at all appreciated by anyone. However, with the help of this simple guide, now you know how you can easily replace the table saw blade on your own within a matter of a few minutes.
