Single- or multi-tooth cutter?

The question of the ideal milling cutter is dependent upon the material to be machined. A single-tooth cutter is often an advantage for "soft" materials (PVC, Perspex, Kömacel, etc), wooden materials (chip- or flakeboard) and non-ferrous metals (soft aluminium, Alcubond, etc.), as the problem of cutting erosion in comparison to clogging recedes.

A double flute is better suited to very hard plastics and harder types of aluminium (short chipping). Milling cutters with 4 or more flutes are predominantly used to mill metals.


   Single-tooth milling cutters
Single-tooth milling cutters are mainly used for machining "soft" materials. Their extra large chipping space guarantees an ideal chipping removal and high stock removal rate.

Multi-tooth milling cutters
Multi-tooth milling cutters are used for machining "harder" materials. Smoother running is achieved, as several cutting edges are always in contact. The more flutes the tool has, the smaller the individual chippings will be. A further advantage of the multi-tooth cutter is a higher quality surface.






Shape A:
Cutter diameter smaller than the shank diameter


Shape B:
Cutter diameter the same as the shank diameter
