3/8 x 4 Down-Cut Spektra Extreme Tool Life Coated Spiral Plunge Bit, 2-Flute, 3/8 Shank

Great for production settings and excellent for creating grooves and dado cuts in softwood, hardwood, plywood and composite materials. 'Down-Cut' spiral. Three-flute design for very high quality finish.

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.

Benefits of Mirror-Finish:
• Razor sharp cutting edge
• Effortless chip removal
• Helps prevent chip re-welding
• Extends tool life
• Exceptional cut quality
• Dissipates heat well and prevents melting

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
• Note: Blue based color dissipates immediately upon use. nACo nanocomposite coating will not wear off
• Note: Designed with extra-long cut length, specifically for cutting for guitar bodies
• Recommended RPM 20,000-21,000
