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. This working surface is flat and presents a cutting edge or point around its periphery. A recess extends into the substrate from the interface. The recess has a side wall and a base both of which are located entirely within the carbide substrate. The recess has a portion located in the interface. The area of this portion is at least 25 percent the area of the interface. A material, different to that of the substrate, fills the recess and is bonded to the substrate. This material will typically be abrasive compact of the same type as the abrasive compact layer, or a cemented carbide which has characteristics different to that of the substrate.
