- 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.
- 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)
