Irwin Blue Groove 4X Flat Bit 32mm x 152mm

The Irwin IRW10502820 Blue Groove 4X Flat Bit is engineered for efficiency and precision in woodworking. Featuring a patented groove point and cutting edge, this bit is designed to cut rather than scrape timber, delivering faster performance compared to standard flat bits. The design includes a parabolic scoop to optimize control and the removal of wood chips, helping to maintain a smoother workflow. An increased relief angle of 17° (up from 12°) reduces dwell time and improves cutting efficiency. The bit also emphasizes durability with a shank that is 152 mm in length and 10% larger in diameter than standard, providing added rigidity during operation. With a 32 mm diameter, this bit targets medium-to-large scale milling tasks while maintaining balance and stability in guided applications.
