Circular saw: Miter cut - this is how it works

When it comes to sawing precise mitres, the table saw is often a good tool. How to deal with it correctly and what you have to pay attention to when sawing mitres, you can read in this article.

How to saw miters?

Miter cuts are oblique cuts, the angle of which has to be exactly right. You can of course also make these cuts by hand - but it is much easier with a circular saw.

When it comes to miter cuts, a distinction must be made between two types of cuts:

  • for example, if you want to cut a board with an angular edge to build a frame, for example
  • if you want to miter cut a square timber

Both can be done relatively easily with the circular saw. The prerequisite, however, is that the circular saw saws exactly (adjust if necessary) and has the correct angle.

Angled cut of an edge

You can easily use an angle stop or a cross stop for this. As a rule, the cross stop is the better variant, which often produces more precise cuts - however, cross stops are not available or can be retrofitted on all circular saws.

If you have a miter value (usually miters are cut at a 45 ° angle)

Miter cut on a square timber

With almost all circular saws, the saw blade can also be tilted at a 45 ° angle. Depending on the quality of the circular saw, this angle is more or less exact. In addition, possible side runout (play of the shaft or flange) plays a major role in the cutting accuracy of mitres.

Always check, adjust if necessary and always measure the cutting result. For this, a simple set square is usually sufficient, the sloping edges of which are also at a 45 * angle. It just has to be created and then shows the exactness of the cut relatively precisely.

Tips & Tricks You should never blindly rely on scales, settings and classifications. Always carry out a test cut (do not work directly on the workpiece) and then check the test cut for accuracy. If larger deviations occur, readjust accordingly. Large deviations can often occur with inexpensive circular saws.
