The Bosch 15 Piece Mixed Drill Bit Set is a versatile mixed drill bit set covering metal, masonry, and wood applications in a single, well-organised kit. Supplied with five precision-ground HSS metal drill bits, five carbide-tipped masonry drill bits, and five wood drill bits with a centering tip, this set covers the most common drilling tasks encountered on site or in the workshop. All bits are available in diameters of 3, 4, 5, 6, and 8mm, making the set suitable for a wide range of everyday drilling requirements. The straight shank design ensures compatibility with standard chucks across most power tool brands, whether you're using a cordless drill or a mains-powered machine. A 118-degree drill tip angle on the metal bits promotes accurate entry and clean hole formation in steel and similar materials. Everything stores securely in the included plastic carry case, keeping each bit protected and readily accessible. This makes the set a practical addition to any tradesperson's kit bag, offering a reliable mix of drill bit types without the need to source them separately.
