About this product
The Bahco 9631 is a long flat wood bit designed for deep or awkward drilling, such as large waste pipe runs and ventilation work through thick timber. It measures 28mm in diameter and 400mm overall, giving extra reach beyond a standard flat bit.
Made from high-carbon steel and heat-treated throughout, the blade is forged directly from the round shaft for strength when drilling larger, deeper holes. Its positive cutting angle allows faster drilling and longer life than a conventional flat bit, while winged shoulders cut the wood's perimeter before clearing the centre, giving a smooth finish and good swarf clearance.

- Positive cutting angle for doubled drilling speed and tripled lifespan
