Abstract (en)
A tip insert (4) for a cutter tool (1) comprises a body (10) of a wear-resistant material (e.g. cemented tungsten carbide) and a disc-like cutting member (11) of a more wear-resistant material (e.g. polycrystalline diamond, conveniently in the form of a layer bonded to a cemented tungsten carbide substrate) secured to the body, the disc-like cutting member having at one part of its periphery its edge shaped to form a flat face (16), so as to provide, with one of its major faces (14), two flat faces (14, 16) disposed in intersecting planes, and the disc-like cutting member (11) being bonded via these two flat faces to complementary plane faces (12, 13) on the body, and the disc-like cutting member having exposed, cutting faces (15) at that part of its periphery opposite to the bonded faces.
