How to Change Blade on Miter Saw

1 step

Make sure that the miter saw is unplugged before you change the blade. It will probably go without saying, but you don’t want to risk getting injured by the miter saw. Safety first!

2 step

Loosen the clamping nut on the end of the arbor. This is the part that holds the blade in place while it spins. Use a wrench or pair of pliers to do this for you. You might need someone else to hold the saw steady while you do this. The last thing you want is for your miter saw to tip over during this process because it’ll ruin your blade, and possibly injure anyone nearby.

3 step

Once you’ve loosened the nut, pull the old blade off of the arbor with your fingers, or use your pliers if possible. Make sure not to put any stress on any parts except where they go into each other (e.g., no trying to “pop” the teeth into or off of the arbor). If you do this, then your blade could snap at any moment.

4 step

Replace the old blade with the new one. Make sure to align things so that they attach correctly to the motor before tightening them down, and replace any parts necessary (like the retaining bolt). By keeping these steps in mind when you’re using your miter saw, whether, for business or home projects, you’ll avoid injury and do better work.

5 step

Put away all tools and try cutting something now! With your newly sharpened miter saw blade spinning merrily along, it’ll be able to slice through the wood for years to come without trouble.

Why Change Miter Saw Blade?

If your miter saw blades are not sharp, they will not produce clean, smooth results. In fact, dull blades can result in splintering or tearing as well as poor accuracy. Knowledgeable woodworkers know that it’s essential to maintain their saws for optimum performance, which means changing out worn saw blades on a regular basis.

There are two main reasons to change your miter saw blade. First, if you are re-sawing or cutting a different piece of wood with the miter saw it may be necessary to use a new blade. Second, it is always a good idea to switch out blades after long breaks in their use. This will prevent accidents brought about by using a dull blade again.

When Should You Change Miter Saw Blade?

Here are the cases when you should replace your miter saw blade:

  • If the cuts are not smooth or if they produce burning or splintering of the wood fibers. If there is some tear-out on the backside of your cut. If there are any cracks near to tooth tips of your saw’s blade. If you have noticed unusual noises coming from it while cutting through the material, which may indicate that something is wrong with either arbor bearings or teeth on your miter saw blade.
  • If you notice any visible cracks in the blade body. If your miter saw is equipped with electronic control and prompts you to replace its blade, it is a good idea to do so right away.
  • If the blade is embedded into the material, don’t use power tools to try and pry it loose. You risk breaking either the blade or teeth on the saw’s arbor. Instead, make a cut with an extremely sharp knife about 1/4″ from each side of the blade and carefully work your way up until you can separate wood fibers surrounding the blade with your hands.
  • Feeling any unusual noise coming from the miter saw while cutting
  • The miter saw is prompting you to change the blade.
