ABSTRACT:
A chisel and a method of manufacturing a durable chisel. An axial hole is formed in a chisel so that the hole is open at the chisel tip. Non-metallic powder is then supplied into the axial hole. A core member made of cemented carbide or other material harder than the chisel body is then press-fitted into the axial hole. By inserting the core member into the hole, the non-metallic powder flows so as to fill up any space between the rear end face of the core member and the closed end of the axial hole.
