Description

Solid carbide jobber drill, SuperLine, 3 x D, shank according to DIN 6535-HE, with internal cooling 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. Versatile jobber drill for drilling holes up to 3 x D with highest cutting values. Particularly suitable for long and short-chipping materials such as GGS and ADI, casting materials, grey cast iron, nodular graphite iron and malleable cast iron, high alloy AlSi alloys and alloy steels up to 1200 N/mm² in strength. With twisted internal cooling through the bar.
