- EXTREME 2™ Metal tip starts drilling on contact eliminating walking for clean, accurate holes (diameters 4.8mm and above only). - Innovative tapered web greatly reduces breakage. - No-slip shank with 3 flats eliminates slipping in the chuck (diameters 5.0mm and above only).
-A complete range of metal drill bits designed and optimised for use with impact screwdrivers. - One piece design, optimised spiral angle and hardening process that guarantees extreme durability inimpact screwdriver applications.
- High performance twist drill for all-purpose use in drilling machines and cordless drills. (Materials up to 5,0 mm thickness) - The 3-surface-shank provides an excellent fixing within the drill chuck with little effort. In addition, the shank ensures an ideal power transmission. No spinning of the drill! - The 135º high performance cutting edge ensures a very high aligned preciseness, particularly when hand-operated with a cordless drilling machine. The edge prevents sliding off corrugated surfaces whilst spot-drilling. - Increased wear resistance of the rechargeable battery due to reduction of cutting forces. - The black bevel increases the wear resistance and prevents cold welding and build-up edges. - The 40º helix angle enables a perfect and fast chip removal and provides a high cutting speed along with increased stability and accuracy. HSSE-Co 5: - Heavy-duty high speed steel with 5 % cobalt content.
- Main use Steel (N / mm ²) <900, Steel (N / mm ²) <1100 - Secondary use Steel (N / mm ²) <1300, aluminum, brass, bronze, synthetic materials and cast iron
