Abstract
A tool component comprises an abrasive compact layer bonded to a cemented carbide substrate along an interface. The abrasive compact layer has a working surface on a side opposite to the interface which is flat and which presents a cutting edge or point on its periphery. A recess is provided, that recess extending into the substrate from the interface. The recess has a shape, in plan, of at least two strips which intersect. Examples of suitable shapes are V-shape and cross-shape. Abrasive compact fills the recess and is bonded to the substrate.

A tool component comprises an abrasive compact layer bonded to a cemented carbide substrate along an interface;
- the abrasive compact layer having a working surface, on a side opposite to the interface, which is flat and which presents a cutting edge or point on its periphery;
- a recess extending into the substrate from the interface, the recess having a shape, in plan, of at least two strips which intersect, each of said strips being of substantially constant cross section and having ends which form a surface in common with the periphery of the cemented carbide substrate;
- and
- a material filling the recess and being bonded to the substrate, the material being different to that of the substrate.
