High-performance rolled, steam-treated jobber twist drill made from heavy-duty black 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).
19 Piece Set available up to 13mm Drill Diameter.
