IRWIN Blue Groove 4X Flat Bit Set, 17 Piece
Professional 17-piece flat bit set with patented Blue Groove 4X technology for 4x faster wood drilling performance.
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.
