4X Groove Flat Wood Drill Bit 25mm

The 25mm IRWIN® Blue Groove 4X Flat Bit is a highly capable size ideal for large-scale construction applications in timber, perfect for substantial pipe installations, major electrical work, and heavy-duty carpentry projects. This diameter is frequently specified for creating clearance holes for 25mm waste pipe and similar large fittings. The patented groove point and cutting edge design ensures this 25mm bit cuts cleanly through timber rather than scraping, delivering smooth, professional-quality holes with minimal effort. Operating up to 4 times faster than conventional flat bits, it dramatically reduces drilling time on larger diameter holes, significantly improving project efficiency. The parabolic scoop efficiently manages wood chip removal whilst maintaining superior control throughout the drilling operation. Engineered with an increased 17° relief angle for optimal cutting efficiency and featuring a 152mm shank that's 10% larger in diameter, this bit offers exceptional durability for demanding applications. The robust construction resists bending and wear, ensuring consistent performance even under intensive professional use.
