Abstract

The rotating tool, in particular a drill, includes a fluted cutting shank made of a resistant material, in particular carbide, extending in an axial direction along a rotational axis. Connecting to the cutting shank in the axial direction is an intermediate shank made of a material of greater elasticity in comparison the resistant material, in particular of tool steel. The intermediate shank includes an insertable cutting insert that may be exchanged. The cutting shank is preferably a cutting shank recycled from a used solid carbide drill.
