An abrasive tool insert includes (a) a substrate having a support face that includes (1) an inner support table, (2) an outer shoulder having a width, S, and (3) a downwardly sloping interface from the support table to the shoulder, which interface has a slope angle, S. A continuous abrasive layer, integrally formed on the substrate support face, includes (1) a center having a height, D, (2) a diameter, D, (3) a periphery having a height, D, in contact with the shoulder and which periphery forms a cutting edge. S:Dranges from between 0 and about 0.5. For each Sand S:D, D:Dis selected so as to diminish residual stress in the abrasive layer.
