Abstract

Abstract A cutting component comprising: (a) a composite abrasive compact comprising an abrasive compact (24) bonded to a cemented carbide support (26); (b) an elongate, cylindrical pin (10) having end surfaces (12,14) and a side surface (16); (c) a recess (20) for receiving the composite abrasive compact sloping from one end surface (14) of the pin to the side surface (16); (d) the composite abrasive compact being located in the recess (20) and bonded to the pin such that the abrasive compact (24) presents a cutting edge (28) for the cutting component and the abrasive compact lies wholly within the side surface (16) of the pin and an imaginary extension thereof; and (e) a groove (32) in the recess (20) which spaces the abrasive compact (24) from the pin (10).
