The IRWIN® Blue Groove 4X Flat Bits are engineered for fast, clean timber cutting. Featuring a patented groove point and cutting edge, they slice through wood rather than scrape it - delivering up to four times the speed of standard flat bits.

A parabolic scoop enhances chip removal and drilling control. The relief angle has been increased from 12° to 17° for improved cutting efficiency. Each bit includes a 152mm shank that is 10% larger in diameter for added strength and durability.
