The Bahco 9629-40 Flat Bit with 40mm diameter is the largest in the range, designed for heavy-duty construction and structural applications. With a working length of 75mm and overall length of 160mm, this substantial size is perfect for drilling holes for large waste pipes, significant ventilation ducting, substantial cable bundles, and sizeable fixings in structural timber, beams, and joists. Engineered with a positive cutting angle, this 40mm bit drills holes twice as fast whilst lasting three times longer than conventional flat bits. Made from high-carbon steel and heat-treated all over, the hardened blade is forged directly from the round shaft for exceptional durability. Its winged shoulders enable the bit to first cut the wood and then remove material from the centre section, ensuring a smooth finish and superior swarf clearance.
