Product details : GUHRING 05511 012.500 RATIO DRILL/COOLING SOLID CARBIDE 12.500MM
Guhring Number 5511
5xD 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, 5 x D, shank according to DIN 6535-HA, with internal cooling
With twisted internal cooling through the bar. Twisted internal cooling. The coolant directly accesses the blades and flushes the chips out of the hole.
Design: Right cutting, with special grinding. The drill has a very good self-centring behaviour and produces short chips, even from long-chipping materials.
Application: Versatile jobber drill for accurate holes 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 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.
