The Bosch 3 Piece Countersink Bit Set is a professional HSS countersink set designed for smooth, chatter-free countersinking and deburring in soft materials, including wood, plastics, and non-ferrous metals. Each bit features five 90-degree cutting edges ground from HSS (high-speed steel), delivering an optimum surface finish across all three diameters. This multi-edge design ensures continuous, burr-free cutting without chatter — ideal for carpenters, joiners, and contractors who need clean, consistent countersinks for screw fixings. The cylindrical shank is compatible with standard three-jaw drill chucks, making these bits straightforward to fit to most corded and cordless drills. With three diameters included, the set covers a practical range of screw sizes in a single purchase.
