GUHRING Micro drill WN SC TiALN inner cooling 7xD 0.60mm

Small jobber drill, 5 x D

Design: Right cutting, with special grinding. Normal angle of rake, without core gradient. Drill with internal cooling. The drill has a very good self-centring behaviour and produces short chips, even from long-chipping materials.

Application: Versatile jobber drill for accurate alignment drilling 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 1400 N/mm² in strength.
