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.

CPC classification number: B21C23/147 , B21C25/02 , B21C25/08
Abstract: The invention relates to a method for producing a blank, in particular a blank for the production of a cutting tool, wherein a green body extending in the direction of the extrusion axis is produced from extrusion material by means of an extruder which has an extrusion channel extending along an extrusion axis; wherein the extrusion channel together with a movable mold element forms a die of the extruder; and wherein the mold element is moved relative to the extrusion channel and within said extrusion channel during the extrusion of the green body, whereby the shaping geometry of the die is changed so that the completely extruded green body hereby has a first functional segment and a second functional segment adjacent thereto in the direction of the extrusion axis (4); wherein the two functional segments differ with regard to their geometries impressed by the die.
