Abstract
An abrasive body, particularly a tool insert, comprises an abrasive layer bonded to a substrate along an interface. The abrasive layer extends into the substrate to a depth below the interface at the periphery of the body and defines a continuous border around the periphery of the body. The abrasive body is further provided with one or more projections which extend from the interface into one of the layers. If the projection extends into the abrasive layer it is of the same material as the substrate and integral therewith. If the projection extends into the substrate layer, it is the same abrasive as the abrasive layer and integral therewith.
