Tool material – K or P?

K- oder P-Hartmetall

Once one has decided on hard metal tools, the question remains on whether to use a K or P type. The answer depends on subsequent use and the corresponding strategy.

As a result of their chemical composition, P metals are less prone to crater wear than K ones. They can thus be used after sharpening without re-coating, though with a reduced service life. At the same time, their chemical composition makes continuous de-coating more difficult given the present state of the science.
