RUKO KEB-HSSCo-14.0mm-QuickIn Cobalt Twist Drill Bit 14 mm

Precision drilling in tough materials demands a bit that stays sharp and true. The RUKO KEB-HSSCo-14.0mm-QuickIn is a 14 mm cobalt twist drill bit engineered for steel, stainless steel, cast iron, and non-ferrous metals. Its HSSCo-E high-speed steel with 5% cobalt withstands high temperatures, while the 135° split point reduces walking and thrust pressure. The QuickIn shank with 10 mm flat ensures secure, rapid bit changes in compatible chucks. Ground from solid with a bright finish, it delivers clean holes and long service life in professional workshops.

Who is it for

Machinists, metal fabricators, and maintenance technicians who need a reliable, high-performance drill bit for production drilling or repair work on hard metals. It suits both stationary drilling machines and hand drills with a 10 mm QuickIn chuck.
