Bosch PRO 18 Piece HSS-Co Drill Bit Set

The Bosch PRO 18 Piece HSS-Co Drill Bit Set is a set of metal drill bits designed for drilling stainless steel and other metals.

Each twist drill bit is made from premium high-speed steel reinforced with cobalt (HSS-Co) and ground for heat and wear resistance. The centring tip helps start each hole exactly where you need it, so the bits don't wander and you get clean, precise results.

This set suits construction workers and installers who need long-lasting HSS-Co drill bits for stainless steel. The 18 DIN 338 bits with a 135° point cover diameters from 1mm to 10mm. They are supplied in a PRO Toughbox case, and the cylindrical shanks are compatible with three-jaw drill chucks.
