Ruko Twist Drill Bit 338 Type N HSS Rolled with Reduced Shank 15mm vendor_ARGON flat and wide nose haveOverview 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.
