Description
Ground Twist Drill in high-performance high-speed steel. Drills very cleanly with burr-free hole edges. Immediate drilling start after insertion as no pre-punching is necessary. Shatter stability is increased by up to 50 % as the core diameter increases constantly in the direction of the shank (from diameter3, 2 mm). Triple milled clamping areas prevent the drill from spinning in the machine (from diameter 5.0 mm). for use on: non-alloy and alloy Steel (up to grade of approximately. 900 N per square millimetre), for drilling thin-walled profiles and sheeting up to 5.0 mm plastics and wood.
