Irwin 6 Piece 4X Blue Groove Flat Wood Drill Bit Set

The Irwin 6 Piece 4X Blue Groove Flat Wood Drill Bit Set is a professional wood drilling solution designed to deliver rapid, efficient performance for carpenters, joiners and construction professionals. This comprehensive set features IRWIN's patented groove point and cutting edge technology that cuts rather than scrapes timber, delivering drilling speeds up to 4 times faster than standard flat bits. The Blue Groove 4X design incorporates a parabolic scoop that optimises control and chip removal, preventing clogging and maintaining consistent drilling performance. Each bit features an increased relief angle from 12° to 17°, enhancing cutting efficiency and reducing friction. The 152mm shank is manufactured 10% larger in diameter than standard designs, providing enhanced durability and reduced flex during demanding applications. This 6-piece set is supplied in a practical storage wallet and includes the most commonly required sizes for timber drilling tasks: 10mm, 13mm, 16mm, 19mm, 22mm and 25mm diameter bits. Ideal for installing cables, plumbing runs and general carpentry work where clean, fast holes in timber are essential.
