The IRWIN Long Series Blue Groove 4X Flat Bit is designed for efficient timber drilling. It features a patented groove point and cutting edge to help cut rather than scrape, aiming to increase cutting speed. A parabolic scoop enhances control and assists in removing wood chips. The bit has an increased relief angle to reduce friction, and a longer, sturdier shank profile for durability during use. These design elements collectively support more efficient drilling with improved guidance and chip management.
