GUHRING 05510 007.140 RATIO DRILL SOLID CARBIDE 7.140 MM 3XD DIN 6537K

Guhring Number 5510 3xD Cylindrical shank Solid Carbide Oil feed drill Futura coated ideally suited for drilling of most ferrous and non-ferrous materials From 3-20mm Diameter

Solid carbide jobber drill, SuperLine, 3 x D, shank according to DIN 6535-HA, 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. Twisted internal cooling. The coolant directly accesses the blades and flushes the chips out of the hole.
