About this product
The Irwin Blue Groove 6X extra long wood drill bit, 16mm diameter and 400mm overall length, is designed for drilling larger cable access holes and pipe penetrations through structural timber, walls, ceilings and floors where extended reach is needed. It offers up to 6 times faster drilling penetration than a standard flat bit. The Tri-Flute design speeds up chip ejection, while the full screw tip aids pull-through and positioning. Cutting spurs produce clean holes with minimal break out, and the tapered flute reduces binding for smoother drilling. The bit is heat treated for added durability, making it suited to demanding construction and renovation applications.
