Developed for carpenters, joiners, timber frame installers and general construction professionals requiring rapid drilling of through-holes and cable passages in softwood, hardwood and construction timber.
The Bahco 9629-SET-8 flat wood drill bit set is manufactured from heat-treated high-carbon steel to withstand demanding site conditions and repetitive drilling applications. Each flat wood drill bit features a hardened blade forged directly from the round shank, creating a robust one-piece construction capable of resisting torsional loads during high-feed drilling operations. The positive cutting angle enables faster penetration rates compared with conventional spade bits, making the set suitable for structural timber, roofing applications and first-fix installations.
All drill bits are equipped with a 6.35 mm (1/4″) quick-change hex shank, allowing rapid accessory replacement in impact drivers, cordless drills and standard drill chucks. The lacquered surface finish provides corrosion protection during transport and storage while maintaining cutting performance in professional environments. Compared with standard cylindrical-shank spade bits, the quick-change interface reduces downtime when multiple hole diameters are required on site.
