Abstract
A tool component comprising a composite compact located in a sloping recess in one end of a solid, elongate right-circular cylindrical pin and bonded thereto. The recess is characterized in that it is formed in the pin to one side of a longitudinal plane passing through the central axis of the pin and the base wall of the recess slopes from one end surface towards a side surface. Bonding of the composite compact to the pin is preferably achieved by means of a braze alloy having a working temperature of less than 700.degree. C. and containing silver, copper, zinc, manganese and nickel. The tool component has particular application as a cutting component for a drill bit.
