Bahco 9631-8-400 Long Flat Wood Bit (Spade Drill Bit), 8mm x 400mm

Bahco 9631-8-400 is an extra-long flat wood bit designed for deep, accurate drilling in timber where a standard spade bit cannot reach. With its 400mm overall length, this spade drill bit is a practical choice for installers and trades who need controlled access through joists, studs and other timber sections.

The 9631-8-400 combines a precision-ground tip for clean positioning with a flat blade profile that helps clear material efficiently, supporting fast progress on site while maintaining a tidy hole finish.

Key Features
