How To Cut An Acute Angle On A Miter Saw

The above picture shows an example of cutting an acute angle on a miter saw. You will see that the blade does not go through the wood at all. It cuts only along one side of it, which results in less material being removed from the surface when you finish your work.

You may have noticed that the saw blade is angled towards you. That’s because most miter saw blades are designed so that they cut at an angle of around 30 degrees or more. If you want to get really precise, then you can try to make the angle even steeper (like 45 degrees) but if you’re working with smaller pieces, it won’t matter too much since there will be no need for such precision.

In general, you want to keep the angle between 30 and 45 degrees. This means that the top edge of your piece should be just slightly higher than the bottom edge of your piece. For instance, if you were cutting a square board into four equal rectangles, then the top edge would be about 1/4 inch (6 mm) higher than the bottom edge.

When you’re cutting an angle like this, you’ll notice that the saw blade is going straight down. This means that you can use any kind of fence to prevent the saw from accidentally cutting into your workpiece. For instance, if you have a table vise attached to your miter saw, then it would be easy enough to clamp the fence onto the top of the miter box and keep it away from your work piece.

While this might seem like a rather silly way of setting up your miter saw, it’s actually fairly easy to make the most common cuts. For example, if you’re cutting a square board into equal angles, then you can just clamp a guide piece at exactly 30 degrees and run your workpiece through. You’ll need to do this twice (once for each side) but at least you’ll have a near perfect cut.

What about other common angles?

We’re going to assume that you can find the exact angle you need by combining simple 30 degree cuts. That means that if you want to cut a board into thirds along its width, then you just need to set your blade to 12 degrees.

You’ll see that this same concept will work for most other common angles as well.
