Circular saw: Miter cut - that's how it works

When it comes to sawing precise mitres, the table saw is often a good tool. How to handle it properly and what you must pay attention to when sawing miter, read in this post.

How to saw miters?

Miter cuts are oblique cuts whose angles must be exactly right. Of course you can make these cuts by hand - but it is much easier with a circular saw.

For miter cuts you have to distinguish two types of cuts:

  • For example, if you want to cut a board with an angle edge to build a frame
  • if you want to cut a mitred timber, for example

Both are possible with the circular saw relatively easily. Prerequisite, however, is that the circular saw saws exactly (adjust if necessary) and is angled.

Oblique cut of an edge

For this you can easily use an angle stop or a transverse stop. In general, the transverse stop is the better option, which often produces more accurate cuts - however, transverse stops are not available on all circular saws or can be retrofitted.

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

Miter cut in a square timber

In 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, a possible side impact (play of shaft or flange) plays a major role in the cutting accuracy of mitres.

Always check, adjust if necessary and always measure the cut result. Usually, a simple set square triangle is sufficient, whose oblique edges are also at 45 * angles. It just has to be created and then shows the precision of the cut relatively exactly.

Tips & Tricks

On scales, settings and divisions you should never rely blindly. 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. With cheap circular saws, large deviations can often occur.
