Twist drill, solid carbide, SuperLine
Made of construction: right-handed, with special grinding. Lateral rake angle normal, core thickness greater than normal, no convergence. Drill with very good self-centering properties, producing short chips even when cutting long-chip materials.
Application: twist drill for alignment with tight diameter tolerances and good surface quality. Designed for drilling max. 7 x D holes with high cutting speeds. Designed in particular for long- and short-chip materials such as structural steels and carburizing, cast steels, heat conditioning 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 reaches the blades directly and flushes the chips out of the drilled hole.
