Dapra Corp. has introduced precision-ground Ball Nose inserts with PCD tips. These diamond-tipped inserts reportedly afford unsurpassed tool life for milling soft, non-ferrous materials such as aluminum and graphite. Their expected life is approximately 50 to 100 times that of normal carbide-coated inserts, providing outstanding wear resistance.

PCD-tipped ball nose inserts are precision-ground to provide a sharp, accurate cutting radius. Available with 3/8", ½" and ¾" diameters, these inserts are designed foruse with Dapra's standard steel, carbide-core and carbide-shank cutter bodies.
