- High-performance rolled, steam-treated twist drill made from heavy- duty high speed steel. - The manufacturing procedure (no structural disruption) solidifies the material making it more elasticated. - This makes it more resistant to fracture and suitable for robust drilling units. (e.g. hand-held drilling machines)
- Precision ground twist drill bit for rapid drilling, long life and excellent concentricity. - Manufactured from High Speed Steel to DIN338. - Ground from solid stock right hand cutting, type N flute, precision ground at 118° point angle.
- 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 in impact 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.
- Precision ground twist drill bit for rapid drilling, long life and excellent concentricity. - Manufactured from High Speed Steel to DIN338. - Ground from solid stock right hand cutting, type N flute, precision ground at 118° point angle.
