How to replace a table saw blade

Replacing a table saw blade can seem daunting at first, but with the right steps, it can be a quick and easy process. In this blog post, we will walk you through the steps of replacing a table saw blade, so that you can feel comfortable doing it yourself next time. We’ll also provide some tips to make the job go more smoothly.

How to replace a table saw blade step by step guide:

Here are some steps to replace a table saw blade carefully:

Step 1.

Disconnect the power, and unplug the saw. Be sure to check your device’s manual for specific instructions on how to shut the machine off properly.

Step 2.

Remove dust from underneath the table with a dry cloth or vacuum cleaner so you have easier access to the blade area of your machine. This will help prevent debris from falling into critical components as you work, which can cause damage later on if not cleaned out properly. It will also reduce the risk of electric shock while working on your machine, making it a very important step in this process!

Step 3.

There should be screws holding down a panel that covers access to a wrench that is used for removing or tightening blades, located on the bottom of your saw. Underneath this panel, you should see a wrench (of varying sizes depending on what type of machine you have) that attaches to the arbor nut located at the center or top of your blade.

Step 4.

Once you’ve gathered all your materials, it’s time to begin using your tools! Make sure that everything is placed securely on a table or workbench so they don’t become loose and possibly cause injury while working on your device. When removing blades, be aware of any sharp edges around them as well as the pointed ends of the blade inside its body after being removed from its mount. Also, remember that blades are very heavy, so take care not to drop anything onto yourself by accident! This may lead to injury.

Step 5.

After you’ve determined which wrench fits your blade nut, use it to loosen the nut so that the blade can be removed. If you’ve never done this before, there may be some resistance at first as you break the tight fit between the nut and blade that has developed over time with wear on them both. Apply steady pressure in a clockwise direction. If you’ve removed the nut correctly, it should not be hard to spin when you are loosening or tightening it. However, you’ll want to avoid turning the nut in a counterclockwise direction because this can cause parts of the blade to break off and leave them stuck inside its body.

Step 6.

Once the blade has been removed, you’ll want to use a rag or dry cloth to thoroughly clean off any debris that may have built upon the mounting flange of your saw. Do not use solvents like gasoline, paint thinner, or lacquer thinner because they can damage certain types of finishes. Be sure that no debris remains stuck in the area where your blade was before installing a new one, as this can cause the blade to come loose while spinning and damage it.

Step 7.

After you have confirmed that your mounting flange is completely clean, place the new blade on top of it inside its body. Line up the holes on both sides of the mounting plate.

Step 8.

Grip the handle of your wrench with both hands and begin tightening the blade by turning it clockwise to prevent further damage to the blade. Make sure that you are applying steady pressure as you turn, as this will keep a secure grip on the blade without damaging it or causing injury. If there is no resistance when going clockwise, then the blade nut is not properly secured. Check to make sure the holes are lined up properly and try again. If there is resistance turning counterclockwise, this means that you have tightened the blade too much and it will be difficult to remove. Loosen it by rotating clockwise until resistance has gone away completely.

Step 9.

After the nut has been tightened, you’ll need to adjust your table saw’s blade height. This is usually done by turning a screw or knob located on the side of the machine and raising and lowering the blade until it is at the desired height. There should be markings on either side of this post that indicate where it should be set for a new blade. Once you’ve found the right spot, tighten the knob or screw to lock this height in place


What size wrench should I use?

One of the most critical aspects of replacing a table saw blade is making sure you have the correct-sized wrench. This will vary depending on whether your machine uses metric or imperial measurements, as well as what type of screwdriver head it uses.

Ask an authorized dealer for help if you are unsure of what size to use, as they can provide you with the correct one and show you how to use it.

How to select the best blade for a table saw?

There are several factors you need to consider before purchasing a new blade for your saw. The first one is the size of the teeth. If you want to cut through thicker materials, then go with a larger-sized blade that has more teeth and can do so at a faster pace than smaller ones.

Another important consideration is how long the blade will remain sharp. This is especially important if you are only using the saw occasionally and don’t want to have to replace it frequently.

Are table saw blades reverse threaded?

Table saw blades are not reverse threaded.

When should table saw blades be replaced?

Typically, you will need to replace your blade whenever it is worn down or has enough accumulated damage on its teeth so that the quality of your cuts starts to become compromised. You can tell if this is happening by inspecting it closely while using your machine and checking the cleanliness of the cuts.


Knowing how to replace a table saw blade is a valuable skill for any woodworker. It can be intimidating at first, but once you get the hang of it, replacing your blades will become second nature and make your job easier.
