Countersink Bosch 2608585740

The Bosch Countersink 2608585740 is an arbour-mounted countersink designed to drill, countersink and deburr wood in a single operation. Intended for use with drill drivers and drill stands, the tool mounts on a brad point drill bit (brad point not included) and combines a 90° countersink with five cutting edges for precise, clean results. Made of tool steel, it can also serve as a depth stop and is suitable for hard and soft wood, laminated and non-laminated chipboard and plywood.

Advantages

The arbour-mounted design performs drilling, countersinking and deburring in one step, reducing setup and work time. Five cutting edges deliver clean cuts and smooth countersinks while the 90° angle produces standard, flush seating for screw heads. Constructed from tool steel for durability and supplied with a hexagon pin key for secure mounting.

How to use

Fit the countersink onto a compatible brad point drill bit and secure it in the drill chuck or arbour according to the drill manufacturer's instructions. Set the required depth using the countersink as a depth stop if needed. Operate the drill at an appropriate speed for the workpiece material, apply steady feed pressure and allow the five cutting edges to produce a clean countersink and deburred hole. Remove the tool and inspect the seat for the screw head; repeat if further material removal is required.

Recommendations

Use the countersink with the correct brad point diameter for accurate centring, choose moderate drill speeds for laminated or veneered surfaces to avoid chipping, and wear appropriate eye protection. Do not use the countersink on metals unless specified by the manufacturer.
