Tooth pitch selection





Choosing tooth pitch for solid materials


The decisive factors for the choice of tooth pitch are the length of the uninterrupted part of the cut. In the case of solid material it is the diameter of the material, in the case of bundle cutting it is their sum.

Choosing tooth pitch for profiles


When cutting profiles and tubes, the choice of the correct tooth pitch is particularly important. The required toothing depends on the material diameter and wall thickness. If you are cutting two or more profiles side by side, double the wall thickness must be taken into account.
