Bosch EXPERT SelfCut Speed Spade Drill Bit 40 x 400 mm (Working Length 350 mm)

This 1-piece Bosch EXPERT SelfCut Speed Spade Drill Bit 40 × 400 mm (working length 350 mm) creates straight, accurate holes in timber. The flat bit handles softwood and wood-based boards such as particleboard or chipboard. For large installations, fixings, and general construction tasks, carpenters and electricians can use this attachment. The cutting geometry integrates a spade-style profile to accelerate chip clearance during heavy use. By reducing the manual pushing force required, the tool helps maintain drilling efficiency across multiple applications. Fast material removal prevents the hole from clogging when working through deep sections of structural wood.

The tool connection relies on a standard hex shank design. This format ensures broad compatibility with electric drills, impact drivers, and common bit holders. Because the angular shaft prevents slipping inside the chuck, rotational power transfer remains consistent. Standard power tools drive the accessory, removing the need for highly specialised equipment. During repetitive overhead or horizontal tasks, the continuous mechanics minimise operator fatigue. A single-purpose design focuses entirely on wood penetration, ensuring predictable results on site.

• 40 mm cutting diameter bores wide channels suited for routing electrical cables and plumbing pipes.
• 350 mm working length out of a 400 mm total span enables deep hole penetration in a single pass.
• 6.35 mm shank diameter fits standard impact drivers and keyless drill chucks securely without adapters.
• Threaded self-feeding tip draws the tool into the material, lowering the required manual pushing force.
• 200 g total weight keeps the drill attachment manageable during extended overhead or horizontal applications.
