IRWIN Blue Groove 4X Flat Bit Set, 17 Piece

The IRWIN Blue Groove 4X Flat Bit Set revolutionises wood drilling with its patented design. Featuring a unique groove point and cutting edge, these bits cut through timber efficiently rather than scraping, achieving 4 times faster performance than standard flat bits.

The parabolic scoop design optimises control and wood chip removal, while the increased relief angle (17° vs standard 12°) ensures smoother operation. Each bit has a 152mm shank length with 10% larger diameter for enhanced durability during rigorous use.

This comprehensive 17-piece set comes in a protective nylon case and includes the following sizes: 6, 8, 10, 12, 13, 14, 16, 18, 19, 20, 22, 24, 25, 28, 32, 35 and 38mm.
