Irwin IRW10507764 3 Piece 6X Blue Groove Power Drill Bit Set 20-25mm
- The Blue Groove Power is the world's first wood drill flat 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 25 mm
