Apparatus and method to provide a rotary dressing tool, formed to the geometric shape of any part piece to be ground, which is utilized to reform an abrasive wheel so that it will produce desired dimensional characteristics on the part piece. A combination of diamond particles and preformed polycrystalline diamond segments are spaced around the outer perimeter of the tool and surrounded by a matrix of abrasive resistant nickel based alloy. Co-utilization of the diamond particles and the preformed segments creates a rotary dressing tool which is highly resistant to abrasive wear, enhancing the performance and durability of the tool.
