PRO Soft Metal HSS Countersink Drill Bit

The Bosch PRO Soft Metal HSS Countersink Drill Bit in 8.3mm offers a step up in size, making it a versatile choice for deburring and countersinking slightly larger pre-drilled holes in soft, non-ferrous metals such as aluminium and copper. Made from high-speed steel (HSS), this bit delivers the strength and heat resistance needed for reliable, long-lasting performance on site or in the workshop. Three 90° cutting edges ensure each countersink hole is clean and free of burrs, giving you a professional result every time. The cylindrical shank fits securely into standard three-jaw drill chucks, making it straightforward to use with most power drills.
