GUHRING For.hel.TB carb.mono. FIRE arrosage central queue 6537-HA 5xD 4,80mm

Solid carbide jobber drill, SuperLine, 5 x D, shank according to DIN 6535-HA, with internal cooling

Design: Right cutting, with special grinding. The drill has a very good self-centring behaviour and produces short chips, even from long-chipping materials. Application: Versatile jobber drill for accurate holes with narrow Ø tolerances and good surfaces. Suitable for drilling holes up to 5 x D with high cutting values. Particularly suitable for long and short-chipping materials such as construction and case-hardening steels, steel castings, tempered steels, carbon steels, bronzes, castings, high alloy AlSi alloys and alloy steels up to 1200 N/mm² in strength.

With twisted internal cooling through the bar. Twisted internal cooling. The coolant directly accesses the blades and flushes the chips out of the hole.
