Ruko Twist drill DIN 338 type N, HSS rolled with reduced shank

Twist drill DIN 338 type N, HSS rolled with reduced shank​

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).

Ideally suitable for drilling larger drilling diameters on all commonly-used drilling machines with a clamping chuck up to 13,0 mm.
