Abstract
A percussion tool for comminuting materials, in particular wood waste materials, having a beater head and a shank, wherein a cutting insert with an upper cutting edge extending transversely with respect to the cutting direction is fastened on the beater head. If the cutting insert has at least one first cutting element and at least one second cutting element, and if a free space in the shape of the upper cutting edge is arranged on the beater head in the cutting direction behind the cutting insert, then the cutting elements are thus supported over a greatest possible surface and are connected with the beater head. It is thus possible to transfer greater forces into the beater head without it being broken off.
