Bosch Professional HSS-Co PRO Stainless Steel Twist Drill Bit 12mm (Pack of 5)

Summary

The Bosch Professional PRO Stainless Steel HSS-Co Twist Drill Bit is a premium cobalt-alloyed metal drill bit designed for construction workers and installers who regularly drill in stainless steel and other tough metals. Supplied in a pack of five 12 mm bits, it combines superior heat resistance with long service life. The bits are precision-ground to DIN 338 and are compatible with standard rotary drills and drivers.

Features

• Manufactured from alloyed high-speed steel with 5% cobalt (HSS-Co) content for significantly enhanced heat and wear resistance over standard HSS bits.
• Fully ground flutes deliver a precise, clean bore in stainless steel, alloyed and non-alloyed steel, cast steel, cast iron, and acid/heat-resistant steels.
• 135-degree self-centring split-point tip allows drilling to start exactly on mark without pre-punching or pilot drilling.
• Two cutters and two flutes efficiently evacuate chips, extending bit life during demanding applications.
• Manufactured to DIN 338 Type N (standard flute angle), with diameter tolerance h8 for consistent fit and finish.
• Gold-coloured cobalt finish provides easy visual identification and indicates premium cobalt grade.
• Suitable for pre-drilling holes for anchors, rivets, threads, and fixtures in steel profiles and beams.
• Compatible with standard drill chucks - not SDS; suitable for use with pillar drills and drill stands.
