The invention relates to 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 in respect to the cutting direction is fastened on the beater head. If the cutting insert has at least one first 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, the cutting elements are supported by this over the greatest possible surface and are connected with the beater head. It is possible by means of this to transfer greater forces into the beater head without it being broken off.
