GUHRING 05510 017.500 RATIO DRILL/COOLING SOLID CARBIDE 17.500MM

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.
