The invention relates to a cermet product and a method and apparatus for the manufacture thereof in which carbonaceous material is placed in a cell in the presence of metal and converted to diamond form. The converted charge upon removal from the apparatus is shaped and mounted on a tool holder and it is then adapted for use as a turning tool. The invention contemplates conversion of the carbon-metal charge in a shaped cavity to reduce the amount of shaping required after the charge is removed from the chamber in which it is converted. |
