Zusammenfassung:	An abrasive tool insert if formed from a substrate having a face and a continuous abrasive layer having a center, a periphery forming a cutting edge, being integrally formed on the substrate, and defining an interface therebetween. The interface is formed in a sawtooth pattern of concentric rings extending from said center to the periphery. Radially outwardly sloping troughs extending from the center to the periphery are superimposed on the concentric rings. The profile of the interface slopes downwardly from the center to the periphery. The abrasive layer advantageously is diamond and the substrate advantageously is metal cemented carbide.
