About this product
This Irwin Blue Groove 6X wood drill bit measures 14mm in diameter and 400mm (16in) overall length, giving the reach needed to drill through structural timbers such as joists, wall studs and floor beams, or straight through walls, ceilings and floors for running cables and pipes.
It claims six times faster penetration than a standard flat bit, thanks to its Tri-Flute design, which speeds up chip ejection and helps prevent clogging. A full screw tip aids pull-through and ease of use, while precision cutting spurs give clean holes with minimal break-out on exit.
The bit is heat treated for durability, and a tapered flute reduces binding, allowing smoother drilling even at awkward angles or through dense hardwoods. Working length is 100mm.
