Product description
MAPAL has developed the Tritan Drill Alu especially for the high-feed machining of aluminium. The three-edged solid carbide drill has a coordinated, finely ground groove profile. Large chip spaces and a special, sharp cutting edge preparation ensure optimum chip formation, reduce heat build-up and ensure the reliable removal of the chips. The special drill tip of the Tritan-Drill-Alu enables drilling on uneven and critical surfaces as well as safe centering.
