Bosch Professional

The Bosch PRO 25 Piece HSS-G Drill Bit Set is a comprehensive metal drill bit set covering diameters from 1mm to 13mm, designed for tradespeople who need precise, long-lasting performance across a wide range of materials. Ground from premium high-speed steel, these HSS-G twist drill bits offer strong resistance to wear and heat, making them a reliable choice for drilling in alloyed and unalloyed steel, non-ferrous metals, cast iron, plastics, and wood. The 135° split-point tip allows you to start holes exactly where you need them without the need for a pilot hole, reducing prep time on site. Ideal for construction workers, installers, and contractors, this set covers the full range of common metric drill sizes in a single ProBox case. The cylindrical shank is compatible with standard three-jaw drill chucks, ensuring broad compatibility with most corded and cordless drills. Bosch claim these bits last up to twice as long as a standard Bosch PointTeQ drill bit.
