Solid carbide twist drill, SuperLine, 5 x D, shank according to DIN 6535-HA, with internal cooling
Made of construction: right-handed, with special grinding. Drill with very good self-centering properties, producing short chips even when cutting long-chip materials.
Application: universal twist drill for hole alignment with tight diameter tolerances and good surface quality. For drilling max. 5 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. Spiral internal cooling. The coolant reaches the blades directly and flushes the chips out of the drilled hole.
