Bahco 9631-20-400 Long Flat Bit 20mm 9631-20-400

The Bahco 9631 20mm Long Flat Bit is a long-reach wood drilling bit suited to jobs needing deep, accurate holes, such as plumbing, cable runs, ventilation work and construction where thick timber must be drilled through. Its 400mm length allows it to reach into awkward or deep locations that a standard flat bit cannot.

Made from high-carbon steel and heat-treated throughout, the bit has a hardened blade forged directly from the round shaft, giving rigidity and accuracy when drilling to depth. Its positive cutting angle drills holes twice as fast and lasts three times longer than a conventional bit.

The winged shoulder design cuts the wood's circumference before removing the centre section, giving a smooth bore and good swarf clearance. Supplied as a single 20mm diameter bit.
