RUKO Blacksmith/Reduced Shank Drills200105B
Blacksmith/Reduced Shank, 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). Ideally suitable for drilling larger drilling diameters on all commonly-used drilling machines with a clamping chuck up to 13.0 mm.
