发明名称 Cutting plate and method of pressing a cutting plate
摘要 The cutting plate for a drill bit is press-formed from a powdery starting material. In the process, the cutting plate is arranged horizontally in the press die and the relative movement of top punch and bottom punch with respect to the die is effected parallel to the flank or flanks of the lateral supporting edge or edges. The novel method enables a variety of special design configurations of the cutting plates.
