The precise, high-performance drill bit for machining stainless steel (e.g. V2A, V4A), heat-resistant steels and titanium. Also for general, broad applications in steel up to 1,200 N/mm² and in cast iron.

Fast drilling with optimal chip removal

Large chip areas and small core

Ideal for core holes

Very precise point geometry for precise drill holes

Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified^® Bronze

Notice

The dia. 13.0 mm drill shank has been reduced to dia. 12.7 mm.

Also recommended for use in conventional steel where a longer service life than that of uncoated HSS drill bits is a priority.
