Description
Solid carbide twist drill bit, SuperLine, 7 x D, shank according to DIN 6535-HE, with internal cooling

Design: Right-hand cutting, with special chamfer.Normal side rake angle, core thickness greater than normal, no taper.Drill with very good self-centering properties, producing short chips even when cutting long-chipping materials.

Application: Twist drill for concentricity with narrow diameter tolerances and good surface quality.Designed to drill up to 7 x D holes at high cutting speeds.Particularly suitable for long and short-cut materials, such as construction and carburizing steels, cast steel, heat-treatable steels, carbon steels, bronzes, castings, high-alloy AlSi alloys and alloy steels with a strength of up to 1200 N / mm2.



Spiral grooves supplying coolant.The coolant goes directly to the blades and flushes the chips away from the drill hole.
