Bosch PRO HSS Countersink Bit

The Bosch PRO Steel HSS Countersink Drill Bit in 12mm is a versatile mid-range option, well suited to countersinking and deburring pre-drilled holes in steel where a 12mm diameter is required. It's a popular choice for construction workers and installers tackling a broad range of steel fabrication and fixing tasks. Constructed from high-speed steel (HSS), this bit delivers reliable performance in metalwork applications, resisting heat build-up during extended use. The 90° cutting edges work through soft metal cleanly, leaving precise, burr-free countersink holes every time. The cylindrical shank fits securely into standard three-jaw drill chucks for a stable, no-fuss setup. Features and Benefits: • HSS construction for strength and heat resistance • 90° cutting edges for clean, burr-free results in steel • Precision deburring and countersinking of pre-drilled holes • Cylindrical shank compatible with three-jaw drill chucks
