Irwin® 10507764 Blue Groove Wood Power Bit Set 3 Piece 20 22 & 25Mm

The Blue Groove Power is the world's first wood drill bit to use IRWIN's pioneering bi-metal technology creating a drill bit with unrivalled speed and durability even in nail-embedded wood. Designed for high-speed precision drilling it marks an end to the frustration that tradesmen experience when their drill bits strike a nail frequently causing standard flat bits to become locked or break. The secret behind Blue Groove Power's extraordinary strength is IRWIN's bi-metal technology a composition of two high performance components high speed steel and carbon steel which both have their own attributes and benefits. The high-speed steel edge provides durability and allows nail cutting while the carbon steel body gives the bit flexibility. Each bit in the Blue Groove Power range has a self-feeding tip which helps to pull it through materials as well as three cutting edges which enhance chip removal for a fast clean hole.Sizes: 20 22 and 25mm.PTDIRW10507764
