Abstract

An abrasive body (12, 22) is provided which has high strength and an ability to withstand high temperatures making it suitiable as a tool insert for dressing tools and surface set drill bits. The body (12, 22) comprises a mass of diamond particles present in an amount of 80 to 95 percent by volume of the body (12, 22) and a second phase present in an amount of 5 to 20 percent by volume of the body (12, 22), the mass of diamond particles containing substantial diamond-to-diamond bonding to form a coherent skeletal mass and the second phase containing chromium and a second metal selected from the group of nickel, iron and cobalt, the chromium being in the form of the metal, chromium carbide and/or in the form of an intermetallic compound with the second metal and the second metal being in the form of the metal and/or the intermetallic compound with the chromium. The abrasive bodies (12, 22) are made under conditions of elevated temperature and pressure suitable for diamond compact manufacture.
