Abstract

A tool insert comprising an abrasive compact layer having a working surface and an opposite surface bonded to a cemented carbide substrate along an interface. At least one cemented carbide projection extends through the compact layer from the compact/substrate interface to the working surface in which it presents a matching surface. The total area of the carbide matching surface is less than that of the compact working surface. The cemented carbide projection may take the form of one or more islands, or the form of a skeleton enclosing within it a plurality of discrete abrasive compact zones or sections.
