摘要： A tool component comprising a composite compact ( 1 2) located in a sloping recess in one end of a solid, elongate right-circular cylindrical pin (10) and bonded thereto. The recess is characterised in that it is formed in the pin to one side of a longitudinal plane (26) passing through the central axis of the pin and the base wall (22) of the recess slopes from one end surface (28) towards a side surface (30). 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°C and containing silver, copper, zinc, manganese and nickel. The tool component has particular application as a cutting component for a drill bit.

The base (2) and substrate (5 or 6) are bonded through a high strength metal or alloy (4), as a filler metal, having a thickness of at most 2 mm and a melting point of at least the liquidus point of the hard sintered alloy. The filler metal (4) may be a Fe-Ni, Fe-Ni-Cr or Fe-Co-Cr alloy.
The component may be made sandwiching the filler metal (4) between the base (2) of the compact (1) and the substrate (5 or 6) then heating and melting the filler metal (4) by an electron or laser beam (7).
