Irwin Blue Groove Flat Bit Set 17 Piece IRWIW4041002

The IRWIN Blue Groove 4X Wood Flat Bit Set features a patented groove point and cutting edge that cut timber rather than scrape it. Designed to be four times faster than standard flat bits, it includes a parabolic scoop to improve control and facilitate wood chip removal for smoother drilling. The set uses a 152 mm shank with a diameter 10% larger than standard for added durability and provides relief angled to 17°. Sizes range from 6 to 38 mm, and the bits are stored in a durable branded nylon roll-up pouch for organized access on the job.
