Abstract

A diamond-containing body is provided which is useful particularly as a tool insert. The body comprises a layer of CVD diamond presenting a working surface defining a cutting edge. The layer of CVD diamond is bonded to a substrate along an interface. A pattern of spaced, curved grooves extends from the interface into the substrate up to a depth of 200 microns and extends across substantially the whole of the interface.
