Ground twist drill in high-performance high-speed steel. Drills very cleanly with burr-free hole edges. Immediate drilling start after insertion as no prepunching is necessary. Shatter stability is increased by up to 50 % as the core diameter increases constantly in the direction of the shank (from Ø 3,2 mm). Triple milled clamping areas prevent the drill from spinning in the machine (from Ø 5,0 mm).
For use on: non-alloy and alloy steel (up to grade of approx. 900 N/mm² ), for drilling thin-walled profiles and sheeting up to 5,0 mm, plastics and wood.
