With the Bahco 9629-18 flat wood bit, you can drill clean 18 mm holes rapidly into wood and timber-based materials. The positive cutting angle and dual cutting edges allow the bit to cut smoothly with minimal resistance, reducing heat build-up while efficiently clearing swarf. Its 1/4" hexagonal shank provides a firm hold in standard chucks and bit holders, preventing slipping under torque. Measuring 152 mm in total length with a 42 mm cutting length, this hardened carbon steel flat bit is ideal for routing cables and conduits during carpentry, framing, and renovation projects.
