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.Size: 16 mm.
The Bahco 9629 Series Flat Bit has a positive cutting angle which drills holes twice as fast and lasts three times longer than a conventional bit. Made from high-carbon steel and heat-treated all over. The hardened blade is forged directly from the round shaft. The winged shoulders enable the bit to first cut the wood and then remove the material from the centre section, ensuring a smooth finish and superior swarf clearance.1 x Bahco 9629-30 Flat Bit 30mm
