The Irwin Blue Groove 4X Long Flat Bit in 6mm x 400mm is the ideal choice for precision drilling applications requiring smaller diameter holes through deep timber sections. This compact diameter bit excels at creating pilot holes, drilling for electrical cable runs, and other detailed carpentry work where a narrower bore is essential. The 6mm cutting width combined with the extended 400mm shank length allows you to reach deep into joists, studs, and timber frames whilst maintaining exceptional control. The patented groove point and cutting edge design ensures this bit cuts rather than scrapes, delivering speeds up to 4 times faster than standard flat bits even at this smaller diameter. The parabolic scoop optimises chip removal, preventing binding and maintaining clean, accurate holes. With an increased relief angle from 12° to 17° and a shank that's 10% larger in diameter for added durability, this bit withstands the rigours of professional trade use whilst delivering consistently superior results.
