Bahco 9631-14-400 Long Flat Bit 14mm 9631-14-400

The Bahco 9631 14mm Long Flat Bit is a long-series flat bit designed for deep, accurate holes in timber, useful for reaching awkward spots that standard flat bits cannot. With a 14mm diameter and 400mm overall length, it suits plumbing installations, cable management and general woodworking where depth and precision are needed.

Made from high-carbon steel and heat-treated throughout, the bit has a positive cutting angle that drills twice as fast and lasts three times longer than a conventional bit. The hardened blade is forged directly from the round shaft for strength and rigidity during extended drilling. Winged shoulders cut the wood perimeter before removing the centre material, giving a smooth finish and efficient swarf clearance. Supplied as a single bit.
