The Bosch PRO 13 Piece HSS-G Drill Bit Robust Set is a professional-grade metal drilling kit designed for tradespeople who need precise, reliable performance across a wide range of materials without the need for pilot holes. Ground from premium high-speed steel (HSS-G), these twist drill bits are built for long-lasting durability in demanding site conditions. The grinding process gives each bit strong resistance to wear and heat, ensuring consistent cutting performance over repeated use. The 135° split-point tip allows you to start holes exactly on your mark, making these bits particularly well suited to drilling in alloyed and unalloyed steel, non-ferrous metals, cast iron, plastics, and wood. The cylindrical shank ensures compatibility with standard three-jaw drill chucks. This 13-piece set covers a practical range of diameters from 1.5mm to 6.5mm, making it ideal for construction workers, installers, and contractors who require a versatile drill bit selection for everyday metalworking and fabrication tasks.
