5 Reasons Why Your Miter Saw is Not Cutting Straight 45 Degrees

A miter saw cutting wood at a 45-degree angle in a workshop.

Just like you would have on a table saw, there are several common reasons why miter saws may not cut straight at a 45-degree angle. These include misalignment of the fence and blade, a warped or damaged blade, a misaligned miter saw bevel gauge, a misaligned miter gauge, and improper clamping of the workpiece when cutting bevels.

Misalignment of the Fence and Blade

You may face a problem with crooked cuts if your fence and blade aren’t in line. This works as the main cause for a miter saw not cutting right. I’ve seen it myself with my miter saw! The blade should run parallel to the fence for clean, straight cuts.

But every so often, knocks or bumps can knock them out of sync. If you spot an off cut, stop and check this first! It’s easy to fix – loosen the bolts holding the blade or fence in place, adjust until they’re square, then tighten up again.

Warped or Damaged Miter Saw Blade

bad blade can mess up your cuts. Blades get bent over time. They also wear out and become dull. A warped or damaged miter saw blade will not cut straight at 45 degrees. The saw may start to wobble and the cut will go off track.

Fixing this problem is easy! Take off the old blade and put on a new one. Make sure it’s sharp and clean, without any dents or warps. Then test your miter saw again by making compound cuts on a piece of wood.

Misaligned Miter Saw Bevel Gauge

A miter saw bevel gauge that is not lined up right can make the saw cut wrong. It makes your wood piece tilt to one side or another. This problem messes up your 45-degree cuts. Also, it’s a big reason why woodworkers have problems with miter saws not cutting straight.

So, you should see if your bevel gauge is set right or not. To fix this, you will need to tune the bevel adjustment on the saw until it lines up just right with the blade of the saw.

All good miter saws let you make these fine adjustments easily. If yours doesn’t let you do this, then maybe there’s a problem with how the tool was made.

Misaligned Miter Gauge

One common reason why miter saws don’t cut straight at a 45 degree angle is a misaligned miter gauge. The miter gauge is the part of the saw that allows you to make angled cuts. If it’s not aligned correctly, your cuts will be off.

To fix this issue, you can adjust the miter gauge by loosening the screws and realigning it with a square or protractor. Make sure to tighten the screws back up once you’ve made the necessary adjustments.

By ensuring that your miter gauge is properly aligned, you’ll be able to achieve accurate and straight cuts on your woodworking projects.

Lack of Clamping on the Workpiece when Cutting Bevels

One of the common reasons why miter saws don’t cut straight at a 45 degree angle is the lack of clamping on the workpiece. When cutting bevels, it’s important to securely clamp down the material to prevent it from moving or shifting during the cut.

Without proper clamping, the wood can deflect and cause inaccurate cuts. So, before making any bevel cuts with your miter saw, make sure to use clamps to hold down the workpiece firmly in place.

This will help ensure that you achieve accurate and straight cuts every time.
