4X Groove Flat Wood Drill Bit 38mm

The 38mm IRWIN® Blue Groove 4X Flat Bit is designed for the most substantial drilling tasks in timber, ideal for large diameter waste pipe installations, major cable entry points, and heavy-duty structural construction work. This diameter represents one of the largest in the range, providing maximum capability for demanding professional applications. The patented groove point and cutting edge design ensures this 38mm bit cuts cleanly through timber without scraping, producing smooth, professional-quality holes even at this significant diameter. Operating up to 4 times faster than conventional flat bits, it significantly reduces drilling time on these larger holes, dramatically improving productivity on major projects. The parabolic scoop efficiently manages wood chip removal whilst maintaining excellent control throughout the drilling process. Engineered with an increased 17° relief angle for superior cutting efficiency and featuring a 152mm shank that's 10% larger in diameter, this bit offers exceptional durability for the most demanding professional applications. The robust construction resists bending and maintains accuracy even under sustained intensive use.
