The Irwin Blue Groove 4X Flat Drill Bit Set is an 8-piece collection of high-performance wood bits designed to deliver professional results for carpenters, joiners and general contractors. Featuring Irwin's patented groove point and cutting edge technology, these flat bits cut rather than scrape timber, making them four times faster than conventional flat bits. The innovative parabolic scoop design optimises control whilst efficiently removing wood chips during drilling operations, reducing jamming and improving accuracy. Each bit features an increased relief angle of 17° compared to the standard 12°, enhancing cutting performance in both softwood and hardwood applications. Built for durability on active job sites, the bits feature shanks that are 10% larger in diameter than standard equivalents, reducing the risk of breakage under demanding use. The 152mm shank length provides excellent reach for drilling through studs, joists and other structural timber work. The set is supplied in a robust hard case for organised storage and transport between jobs.
