The Bosch 18 Piece PointTeQ HSS Drill Bit Set is a professional-grade twist drill bit set designed for fast, accurate drilling in metal and a wide range of other materials. The set's defining feature is the PointTeQ tip design, which self-centres on contact to prevent the bit from wandering at the start of a hole. This precision entry point also increases the drilling rate, reducing heat build-up and wear during use — helping the bits stay sharper for longer and extending overall working life. Each bit is manufactured to DIN 338 standard with a Type N flute angle and 135-degree tip, making them suitable for drilling clearance and pilot holes in alloyed and non-alloyed steel, non-ferrous metals, cast steel, cast iron, and plastics. The black-oxide coated flute promotes fast chip removal, keeping the cutting action clean and efficient. The cylindrical shank design is compatible with standard three-jaw drill chucks and is intended for use in drill stands and drill drivers. For smaller diameters below 6mm, the highly elastic body construction significantly reduces the risk of breakage — a practical advantage when working with precision pilot holes. The 18 bits are supplied in a ToughBox case, covering diameters from 1mm to 10mm for versatile day-to-day use on site or in the workshop.
