Bosch PRO 19 Piece HSS-Co Drill Bit Set

The Bosch PRO 19 Piece HSS-Co Drill Bit Set is a cobalt HSS twist drill bit set designed for drilling clean, accurate holes in stainless steel. Each bit is made from premium high-speed steel blended with 5% cobalt. This gives strong resistance to heat and wear, so the bits keep performing hole after hole. A specially designed centring tip helps you start holes exactly where you need them, with less wandering. That makes the set a practical choice for construction workers and installers who need precise, long-lasting bits for stainless steel and other metals. The set covers 19 sizes from 1 mm to 10 mm in 0.5 mm steps, supplied in a compact PRO Box. The bits are made to DIN 338 and have cylindrical shanks that suit three-jaw drill chucks.
