The Bosch 8 Piece Impact Control Metal Drill Bit Set is a professional HSS-G twist drill bit set designed for drilling in steel, non-ferrous metals, and plastics using a drill driver or impact driver. Ground from premium high-speed steel, these bits are built to resist wear and heat, offering long-lasting performance across demanding applications. The 135° split-point tip ensures accurate hole starting without the need for a centre punch, making them a practical choice for contractors and installers working to tight tolerances. The impact-rated ¼” hex shank provides a secure, rattle-free connection in both three-jaw chucks and quick-release impact driver tool holders, maximising torque transfer and drilling efficiency. This makes the set well suited to tradespeople who regularly switch between drill drivers and impact drivers on site. Supplied in eight diameters from 2mm to 10mm, the set covers a broad range of drilling tasks in alloyed and unalloyed steel, cast iron, non-ferrous metals, plastics, and wood.
