Irwin 4X Blue Groove Flat Wood Drill Bit

The 19mm IRWIN® Blue Groove 4X Flat Bit provides a specialist size perfect for specific construction and joinery applications where precise diameter requirements are critical. This size is particularly valuable when working with specialist hardware or creating custom installations in timber. The patented groove point and cutting edge technology ensures this 19mm 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 and improves overall productivity. The parabolic scoop efficiently manages wood chip removal whilst maintaining superior control throughout the drilling process. 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.
