How to cut a 22.5 Degree Angle on a Miter Saw

How to cut a 22.5 Degree Angle on a Miter Saw (And charge like a pro!!!!!)😎

Getting a perfect eight-sided figure (aka 22.5 Angle) isn’t a joke. Especially with a miter saw.

Here is why:

Every model of miter saw doesn’t allow you to cut acute angles perfectly. Besides, operating the miter saw is pretty easy and simple as well.

If you’re a woodworker like me…….you know what exactly I am talking about.

But Anyway… why am I walking you through all this?

That’s because today, we’re gonna talk about how to cut a 22.5-degree angle on a miter saw.

That’s right baby………

It’s time for cutting extreme angels like a ninja woodpecker!

But Why 22.5 on a miter saw?

Ahhhh….You’re smart!

That’s the very first question that should pop up in your mind.

We all have to admit it:

There are other saws like the circular saw or the table saw. They both use a circular saw blade to cut through sheets and woods perfectly.

Why you’re going to choose the miter saw?

Well, the answer is straight at one point, and that is precision and time.

The efficiency and work performance of a miter saw are pretty great. It can give you precise results in no time at all. When you need to cut tiny angles like a 22.5 degree, you can rely on a miter saw. It’ll cut through your piece easily in no time.

Besides, a miter saw is pretty stable as well. You just need to lock in position, lower the handle while pressing the trigger.

You’re all done.

Is it possible cutting a 22.5-degree angle with miter saw blade?


It’s possible to cut a 22.5-degree angle with the miter saw.

Yeah, that’s true. A miter saw doesn’t allow you to cut acute angles or tiny angles, but you can cut it perfectly if you know the exact technique of how it works.

The very first thing you need to do is make a support jig of 45 degrees and attach it to your fence. After placing the jigs perfectly and with proper position calculated, it’s simple to cut a 22.5 degree with a miter saw blade.

But first………How to calculate a 22.5-degree angle?

Understanding the scale of your miter saw is pretty confusing.

Even there are numbers, and you can see those numbers perfectly, you can’t understand what they mean for the first time.

First of all, the 0 point is for 90-degree angle cuts; you need to understand that. While you’re cutting at position zero, you’ll be cutting a 90-degree angle.

Now, if you move left or right, you’ll see there’s a point 10. This scale point means if you set your cut at that 10, it’ll subtract 10 degrees from your 90-degree angle, and you’ll be cutting an 80 degree there.

What’s next?

This scale takes you to 45 degrees highest on both sides. But, your angles are different when you add 45-degree jigs on both sides of the fence. With 45 degree jigs, you’ll be cutting through a 45-degree angle at point 0.

Now, if you set it to 22.5 degree, it’ll simply subtract the number from your 45 degree, and you’ll be able to get your desired angle. This is how you can calculate and lock the position of 22.5 degree.

How to cut a 22.5 degree angle on a miter saw?

Here are the rules you need to follow to perform it precisely. So let’s jump to the main process of how to cut 22.5 degree angle.

Step 1:

Cut 2 45 degree angle jigs and attach them with the fence. You can clamp them with the fence with the lockers. Simply hand tighten them and make sure they’re locked there safely.

Step 2:

Now, move the turntable and set the scale. In terms of getting an accurate 22.5 degree, you need to subtract 22.5 from your 45 degree angle. This will ensure that you’re getting a 22.5 degree angle.

Step 3:

Take your molding or piece and lock it at the position. It’s important to lock the piece in position before you start cutting through it. The miter saw is precise, and it cuts through magically, but you can’t get your desired result if it’s not calculated properly and locked there safely. Your miter saw has clamps that are going to keep it in place firmly. If you don’t know how to adjust the clamps, refer to the user manual.

Step 4:

When everything is set up and ready to go, simply pull the handle of your miter saw down. This is where the main application begins. When it’s one or two inches above your object, simply pull the trigger and lower the handle. The blade will start spinning pretty fast, and it’ll cut through your object in no time.

Step 5:

Hold and release the trigger when cutting is done. Pull the handle up after the blade stops spinning. Let the blade and the miter saw cool down for a while and examine your angle if it’s top-notch.

This is how you can cut a perfect angle of 22.5 degrees. Some miter saws have a scale set that allows you to cut through tiny angles. For those saws, you need to adjust and lock to the number 22.5 degree and cut through your wood. In this process, you don’t need any 45-degree jig support to cut.

However, using the 45-degree jig support is common everywhere, and you’re going to love it using the power of geometry.

How do you join two pieces of wood at a 22.5-degree angle?

When you’re willing to join two pieces of wood at a 22.5 degree angle, there are a few methods that you can apply while you’re making the joint.

How do you construct a 22.5 degree angle?

Sometimes, joining is a big task if you don’t have the proper tools. How do you cut angles greater than 45 degrees on a miter saw? Both 22.5 degrees of angle wood will make it a 45.

  • Take them together and place them firmly. Now use glue to attach them. When done, let the glue dry off.
  • Use the biscuit method to join the two pieces. This method works from the upside of the joint.
  • The same thing goes when you spline the joint. In this case, make sure that your joint is perfect and giving the result of an appropriate angle.

Safety tips: What should you not do while cutting a 22.5 angle with a miter saw?

Safety matters!!!!

I know I said this thousands of times in this blog, but it really is.

The safety precautions must have to be the main priority in terms of cutting through wood with a miter saw. Here are a few tips for safety miter saw cut each & every time.

  • The very first thing is to check the miter saw scale for precise angles constantly. It’s pretty important as your cutting result depends on it. You should not go easy on the scale while you’re cutting acute angles like the 22.5 degrees.
  • Make sure the clamps are tight and you added the jig perfectly to the saw. If you don’t know how to adjust the clamps, you need to go through the user manual. Placing and locking the clamps are essential to get your desired result.
  • Make sure you’re ready with safety gears like protective glass, mask, etc, before you start cutting with the miter saw.
  • When you’re triggering the machine, make sure your hand or other body parts are somehow not near the blade.


See, didn’t I tell you It’s pretty easy and simple?

Just a reminder:

Don’t go fast, work smoothly and accurately.

Make sure your cuts are precise.

And NEVER!!!!

I repeat… Never, ever forget to wear safety gear. By the way, how do you cut a 22.5-degree corner? Let me know in the comment section.

Ciao for now!
