2-1/4" x 0.005" Tip Spektra Extreme Tool Life Coated Signmaking Engraving Router Bit, 1/4" Shank

For extra-fine carving and lettering details. These tools are used for wood, plastic and solid surface materials. Maximum RPM 28,000.

Our Spektra bits feature a nACo nanocomposite coating with an extreme nano hardness and heat resistance. With a brilliant distinctively-tinted coloring nACo provides additional improvements in four critical aspects of router tooling.

Features:
• 0.44" of cutting height
• 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

Note: Blue based color dissipates immediately upon use. nACo nanocomposite coating will not wear off.
