Solid Carbide Spektra™ Extreme Tool Life Coated 2D/3D Carving Straight Ball Nose (Conical Ball) Router Bits with special unique carbide with nACo® nanocomposite coating for longer lifetime.

Specially designed for 2D and 3D CNC profiling and carving in plastic & wood with machines with CNC machines. The high-shear ball nose tips cut smooth 2D and 3D contours with reduced stepping while the proprietary Spektra™ coating (applied by the physical vapor deposition coating process) provides high resistance to wear sharper cutting edges extended tool life and less friction & heat buildup.

Tools are manufactured with high balance that allows them to run up to 60,000 RPMs. Adjust your chip load and feed rate accordingly.


  • A perfect bit for 3D carving

  • 2D and 3D contouring, profiling, modeling and pattern making for cabinetry, sign making, furniture making and jewelry mold making

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.

  • 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.

Milling Plastics

In a milling application all plastics tend to behave differently so attention must be paid first and foremost to heat input as that greatly impacts surface finish and chip control. Some of Amana Tool carving tools as you can appreciate have a very small diameter therefore any material chip-loads need to reflect that small size. It can however withstand RPM’s up to 60,000 RPMs. A directed air-blast to keep chips away along with cooling the tool and work piece are always welcome.

Suggested starting spindle speed might be 18,000 RPM there needs to be some experimenting on the part of the programmer to best find an acceptable finish.

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