Abstract
In a shaft-type cutter body of hard material including a shaft for mounting the cutter in a chuck and a head including cutting areas with cutting edges disposed around the circumference of the head, the shaft and the head are formed integrally by injection die casting of powdered raw material followed by sintering. The unfinished cutter body includes cutting edge sections with recessed areas adjacent the cutting edge front surface area for receiving wood chips and delimiting the cutting edge surface area and a surface area receding radially inwardly from the rear cutting edge surface area of the cutting edge so as to limit the rear cutting edge surface area.
Claims4
A shaft-type cutter body of a hard material, comprising:
- a shaft for mounting the cutter in a chuck, a head including a number of cutting edges formed at least at the circumference of said head, said shaft and said head being formed by injection die casting of powdered raw material followed by sintering thereby providing an unfinished cutter body which includes cutting edge sections with front and rear cutting edge surface areas and recessed areas which are disposed adjacent the cutting edge surface areas and extend radially inwardly beyond the front cutting surface area for receiving wood chips and delimiting the front cutting edge surface area, and a free space formed by a surface area receding radially inwardly from the rear surface area of said cutting edge so as to limit the rear cutting edge surface area.
