46490 K Extra Long CNC 2D and 3D Carving Ball Nose 0.10 Deg Straight Angle x 1/4 Dia x 1/8 Radius x 1/2 x 1/4 Shank x 3 Flute Spektra Extreme Tool Life Coated Reduced Shank Router Bit
These router bits are made with an extra-long reduced shank section for deeper reach and better chip clearance. Amana Tool®s Modern Materials Finishing Geometry (MMFG) incorporates high shear, multi-flute and Spektra coating designed for the ultimate combination of finish and tool longevity in aerospace materials. Modern-day materials present challenges to the fabricator, using these special multi-flute edge tools featuring Spektra ceramic coating addresses these challenges with a winning geometry combination.
Specially designed for 2D and 3D CNC profiling and carving in plastic & wood 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 and heat buildup. 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.
The simultaneous 3 axis motion with the appropriate software allows full 3D capability that provides sign and 3D model makers the ability to work with any material.
Tools are manufactured with high balance that allows them to run up to 60,000 RPMs. Adjust your chip load and feed rate accordingly.

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.
- nACo coating is a micro-thin ceramic coating which enables the tools 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.
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.
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.
