Bosch Wood Countersink Bits

The Bosch Wood Countersink Bit is an arbor-mounted countersink designed to drill, countersink and deburr in a single step — eliminating the need to swap between bits and saving valuable time on the job. Mounted on a brad point drill bit, it delivers all three operations simultaneously for consistently clean, professional results.

Suitable for use on hard and soft wood, laminated and non-laminated chipboard, and plywood, this versatile bit is compatible with drill stands and drill drivers. Constructed from durable tool steel, it features a 90-degree countersink angle and five cutting edges for efficient material removal. The bit can also double as a depth stop for added precision and control. Available in sizes from 3mm to 10mm to suit a wide range of screw sizes and applications.
