- 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)
