ABSTRACT:
Disclosed is an abrasive tool insert having an abrasive particle layer having an upper surface, an outer periphery, and a lower surface integrally formed on a substrate which defines an interface therebetween. The abrasive particle layer outer periphery forms a cutting plane. The thickness of the abrasive particle layer at its outer periphery cutting plane decreases radially inwardly. Thus, the interface can have a sawtooth shape cross-sectional profile, at least one slot extending from said abrasive particle layer outer periphery radially inwardly, or other configuration based on the precepts of the present invention. Also, the angle of the outwardly sloping profile can be matched to the anticipated angle of the wear plane which will develop as the PDC wears in use.
