Bosch PRO HSS Countersink Bit

The 10mm Bosch PRO HSS Countersink Bit is a practical small-to-medium size for deburring and countersinking pre-drilled holes in steel. It's well suited to general fabrication and installation tasks where you want a neat finish on modest-sized holes. Made from high-speed steel (HSS), it offers strength and resistance to heat for dependable use. The 90° cutting edges help you get clean, burr-free countersink holes exactly where you need them. The cylindrical shank is compatible with three-jaw drill chucks, so it works with your existing drill.
