Irwin 4X Blue Groove Flat Wood Drill Bit

The 32mm IRWIN® Blue Groove 4X Flat Bit provides a substantial diameter perfect for heavy-duty construction and installation work in timber. This size is particularly valuable for creating clearance holes for large waste pipes, substantial cable bundles, and major structural applications. The patented groove point and cutting edge technology ensures this 32mm bit cuts cleanly through timber rather than scraping, delivering smooth, professional-quality holes even at this significant diameter. Operating up to 4 times faster than conventional flat bits, it dramatically reduces drilling time on larger 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 in the most challenging environments.
