Description

Solid carbide jobber drill, SuperLine Design: Right cutting, with special grinding. Normal angle of rake, core thickness thicker than normal and without core gradient. The drill has a very good self-centring behaviour and produces short chips, even from long-chipping materials. Application: For accurate holes with narrow Ø tolerances and good surfaces. Suitable for drilling deep holes up to 7 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. The coolant directly accesses the blades and flushes the chips out of the hole.
