About this product
This 20mm Irwin Blue Groove 6X wood drill bit is designed for larger holes needed for waste pipes, electrical installations and cable runs through structural timber. At 400mm overall length, it gives the reach required to drill through thick walls, ceilings and floors in new build or renovation work. The Tri-Flute design speeds up chip ejection, helping maintain cutting efficiency, while the full screw tip aids positioning and pull-through. Cutting spurs produce clean holes with minimal splintering, and the tapered flute reduces binding for smoother drilling. Heat treatment adds durability, and the bit claims six times faster penetration than a standard flat bit. Diameter: 20mm. Overall length: 400mm. Working length: 100mm.
