Bosch Drill Bit and Countersink

The Bosch Brad Point Drill Bit with Countersink in 12mm is the largest in the range, purpose-built for heavy structural timber applications, large-scale joinery and situations where oversized fixings are needed. The 12mm diameter ensures a clean, accurately countersunk hole even in the most demanding hardwood and engineered timber materials. By carrying out drilling, countersinking and deburring simultaneously, this bit dramatically reduces the time spent on repetitive fixing tasks, making it an invaluable addition to any professional's toolkit. It is compatible with drill stands and drill drivers, and the cylindrical shank suits standard three-jaw drill chucks. Constructed from tool steel with five cutting edges and a 90-degree countersink angle, it also serves as a depth stop for repeatable, consistent screw depths. Suitable for hard and soft wood, laminated and non-laminated chipboard, and plywood.
