3mm Dia x 21mm CNC Solid Carbide Spektra Extreme Tool Life Coated Compression Spiral Bit, 2 Flute, 3mm Shank

Special unique carbide for longer lifetime in abrasive material. Designed for CNC applications requiring high feed rates and a clean finish. Particularly suitable for double-sided melamine or laminated material. Flawless compression cuts. Our Spektra bits feature a nACo nanocomposite coating with an extreme nanohardness and heat resistance. With a brilliant distinctively-tinted coloring nACo provides additional improvements in four critical aspects of router tooling.

Features:
• nACo coating is a micro-thin ceramic coating which enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality
• Coating prevents high heat and oxidation which is detrimental to cutting tool performance
• Multi-colored hues, while attractive, will dissipate upon use and yet coating will remain fully effective
• nACo offers approximately 4,500 Vickers for impressive solid hardness on cutting areas of the tool, for an increase up to 2.5 times compared to uncoated bits
• Oriented Strand Board is an engineered wood particle board
• Note: Blue based color dissipates immediately upon use. nACo nanocomposite coating will not wear off
