<p>An abrasive tool insert if formed from a substrate (10) having a face and a continuous abrasive layer having a center (26), periphery forming a cutting edge, being integrally fomred on the substrate, and defining an interface therebetween. The interface is formed in a sawtooth pattern of concentric rings (16, 14, 12) extending from said center to the periphery (28). Radially outwardly sloping troughs extending from the center to the periphery are superimposed on teh concentric rings. The profile of the interface slopes downwardly from teh center to the periphery. The abrasive layer advantageously is diamond and the substrate advantagwously is metal cemented carbide. The invention concerns also a method for forming an abrasive tool insert.</p> |
