Bosch PRO HSS-Co Cobalt Drill Bit 3mm Pack of 1

This cobalt twist drill bit delivers exceptional longevity when machining stainless steel, making it a reliable choice for demanding metalworking tasks. Engineered with high-speed steel and cobalt alloy, it maintains its cutting edge far longer than standard bits, reducing downtime and replacement costs. Whether you are working on sheet metal, pipes, or industrial fittings, this 3mm bit offers the precision and durability needed for consistent, accurate holes.

- Extended service life thanks to cobalt alloy content that withstands high drilling temperatures

- Optimised for stainless steel, but also effective on hardened steels, cast iron, and non-ferrous metals

- 3mm diameter suits small fasteners, pilot holes, and precision work

- 135-degree split point eliminates walking and ensures immediate, clean starts without a centre punch

- Fully ground HSS body with tempered hardness for enhanced wear resistance

- Round shank fits standard 3-jaw chucks on corded and cordless drills

- Suitable for professional workshop use as well as serious DIY applications

- Supplied in a single-bit pack for individual replacement or project-specific needs

Trust in Bosch PRO engineering to deliver the performance and durability required for repeated use in tough materials.
