IRWIN Blue Groove 4X Flat Bit, 40 x 152mm

The **IRWIN Blue Groove 4X Flat Bit** features a patented groove point and cutting edge, designed for efficient timber cutting rather than scraping. Engineered to be four times faster than standard flat bits, this tool significantly enhances drilling performance.

Key to its superior performance is the parabolic scoop design, which optimises control and ensures efficient removal of wood chips during operation. The bit's increased relief angle (from 12° to 17°) further improves cutting efficiency and reduces friction.

Constructed for durability, the shank measures 152mm in length and features a 10% larger diameter than standard bits, providing added strength and longevity. This makes the IRWIN Blue Groove 4X Flat Bit an excellent choice for both professional tradespeople and DIY enthusiasts seeking reliable, high-performance drilling solutions.
