Why Change Miter Saw Blades
There are several reasons you may need to change the blade on your miter saw. Your blade may be dull. You may have a wood cutting blade installed in your miter saw, but need to cut some metal. Or you may have a 24 tooth blade installed that is good for cutting studs, but you want to install a 100 tooth blade to cut some pieces for a furniture project.
Miter Saw Blade is Dull
Probably the most common reason to change the blade on a miter saw is the blade has become dull and no longer produces quality cuts.
What kind of blade should you get if your miter saw blade is dull? That will depend a lot on what type of cuts you’ll be making and we’ll dive into this more in depth below in “Different Miter Saw Blade for Different Cuts”.
In the meantime, if you’re like me and most of your miter saw cuts are for DIY furniture projects I love the Freud 100 tooth Diablo Ultra Fine saw blade. This is the blade I have installed on the miter saw in my small workshop. The cuts are smooth and crisp – exactly what I want for my DIY furniture projects.
Is Your Blade Really Dull?
Did you know a dirty blade can act like a dull blade? With each cut we make wood pitch collects on our miter saw blades. As the wood pitch builds on the blade it can affect the quality of the cuts which makes us think the blade is dull. If left unchecked this wood pitch can also corrode the blade.
How do you remove wood pitch from your miter saw blade? With a special blade and bit cleaner. Cleaning our miter saw blades is so simple and an important part of properly maintaining our tools. Please skate over to Clean Saw Blades for Peak Performance and Quality Cuts to see which cleaner I use, the simple procedure I use to clean my saw blades and saw blade cleaning video.
Different Miter Saw Blade for Materials
Another reason to change the blade on your miter saw is to cut a different material. Saw blades are designed to cut specific materials. Not to make this sound overly simplistic but if you need to cut some wood you’ll want a blade designed to cut wood and if you need to cut some metal you’ll want a blade designed to cut metal.
Different Miter Saw Blade for Different Cuts
Once you have determined what type of material you’ll be cutting the next thing to look at is the number of teeth on the blade. I’m not an expert on saw blade construction, but here’s my simple look at how the number of teeth work on a miter saw blade.
Saw blades with more teeth produce cleaner, crisper cuts, while blades with fewer teeth produce rough, choppy cuts. Blades with more teeth are great for cutting pieces for our DIY furniture projects. Blades with fewer teeth are great for cutting studs to build a house where you don’t care what the cut looks like.
As I mentioned earlier my go-to saw blade is the Freud 100 tooth Diablo Ultra Fine saw blade. This is the saw blade I have installed on my miter saw in my small workshop. I use this saw to almost exclusively build DIY furniture. The cuts are smooth and crisp – exactly what I want for my DIY furniture projects.

How to Change Blade on Miter Saw
This tutorial shows how to replace the saw blade on a 10” Hitachi Miter Saw. Please refer to your owner’s manual for how to change the blade on your specific miter saw. Are you missing the manual for your saw? No worries most manuals for modern tools are available online. Just google the name and model of your saw or tool (ex: Hitachi miter saw manual) and I bet you’ll find the manual for your saw.
IMPORTANT: Always work safely and always disconnect the power plug from the outlet before making any adjustments to your miter saw or replacing the miter saw blade.
Step 1. Remove the Spindle Cover. Rotate the blade guard to the top position. Remove the front screw from the spindle cover and allow the spindle cover to pivot on the back screw and drop out of the way.
Step 2. Remove the Blade. Press the spindle lock to fully lock the spindle. If the spindle lock cannot be fully locked turn the spindle with a 10mm wrench while applying pressure to the spindle lock.
While pressing the spindle lock use a 10mm wrench to remove the bolt. NOTE: This is a left-hand thread bolt which means it must be turned to the right in order to loosen.
Remove the bolt and washer.
Then remove the blade from the miter saw.
Step 3. Replace the Blade. Replacing the blade is opposite of removing the blade. Remember to use the direction arrows printed on the blade to install in the correct direction. Replace the washer and bolt (remember the bolt will turn to the left to tighten). Press the spindle lock and tighten the bolt with a 10mm wrench. Replace the spindle cover screw and lower the blade guard.
NOTE: Be sure the spindle lock is disengaged before turning on your saw.
Tune-Up Your Miter Saw
Over time our miter saws can come out of adjustment. Sometimes even new saws out of the box need to be adjusted. To ensure accurate cuts we need to be sure the blade is square to the table and the fence is square to the blade.
