About this product
The IRWIN Blue Groove 4X Flat Bit is a 32mm diameter wood-boring bit suited to heavy-duty construction and installation work, such as clearance holes for waste pipes, cable bundles and structural applications. Its patented groove point and cutting edge are designed to cut rather than scrape the timber, giving cleaner holes and performance up to four times faster than standard flat bits. A parabolic scoop helps clear wood chips and maintain control during drilling, while the relief angle has been increased from 12° to 17° for more efficient cutting. The shank measures 152mm and is 10% larger in diameter than standard, adding durability for demanding use. Supplied as a single 32mm bit.
