Bosch PRO 18 Piece HSS-G Drill Bit Set

The Bosch PRO 18 Piece HSS-G Drill Bit Set is a professional-grade twist drill bit set designed for drilling in metal, wood, and plastics without the need for pilot holes.

Ground from premium high-speed steel to DIN 338 standard, these HSS-G bits offer exceptional resistance to wear and heat, making them a reliable choice for construction workers, installers, and contractors who require long-lasting performance in demanding conditions. The set is supplied in a compact Toughbox case measuring 180 x 85 x 45mm, keeping bits organised and protected on site.

The 135° split-point tip delivers precise hole placement from the first contact, eliminating drift and reducing the need for centre punching. Suitable for use in alloyed and unalloyed steel, non-ferrous metals, cast iron, plastics, and wood, the cylindrical shank is compatible with standard three-jaw drill chucks.

The set includes 18 bits covering diameters from 1mm to 10mm, with several commonly used sizes duplicated for convenience. Bosch states these bits last up to 2x longer than a Bosch PointTeQ drill bit, offering genuine value for trade use.
