Abstract
A diamond tool comprises a circular core plate and a peripherally attached cutting segment. The cutting segment comprises a plurality of abrasive particles, a holding body that holds the abrasive particles, and a plurality of non-abrasive inserts. The abrasive particles are dispersed within the holding body and the non-abrasive inserts are embedded in the holding body. The non-abrasive inserts are sized and distributed so that the peripheral average density of the abrasive particles in the holding body of the cutting segment varies across the peripheral edge in discrete steps or continuously.
