Spiral drill bit 3xD type 1206

Design: Ultra-finest grain-solid carbide, DIN 6537, type RT 100 U.
Fire coated surface, right cutting with special point geometry and ratio point thinning. 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.

Carbide application group: K/P ?universal use.
(Ultra-fine grain K05?K50/P05?P50)

Application: For accurate holes with narrow Ø tolerances and good surfaces. Suitable for drilling holes up to 3 x D with the best 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.
