Latest Patents

Grubb holds a patent for a "Cold-headed and roll-formed pick type cutter body with carbide insert." This invention features an improved socket for a carbide insert, which is crucial for the performance of the cutter. The cutter body is cold-headed from a steel blank, resulting in a cylindrical shank and a conical head with a socket at the forward end. The design includes a roll-formed cylindrical shank that provides a retaining groove, as well as an extraction groove between the head and the shank. The initial step of cold-heading involves squaring up the forward end of the blank, which is then punched to create a socket of densified work-hardened steel. The completion of the bit is achieved by brazing the base of a carbide insert in a mating relation with the socket in the head. Grubb's innovative approach has led to significant advancements in the design and functionality of cutting tools.
