- 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)
- Particularly suitable for deburring and cleaning pipes, threads, coupling sleeves and cylinders. In addition to a thread, some versions also have a shank: - M6 thread: 6 mm shank; - 3/8 thread: 10 mm shank.
