CNC 3D Taper Ball Nose Cutters

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 vapour 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.
Tools are manufactured with a high balance, allowing 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 nano hardness and heat resistance. With a brilliant distinctively-tinted colouring nACo provides additional improvements in four critical aspects of router tooling.

nACo coating is a micro-thin ceramic coating that enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality.
The coating prevents high heat and oxidation, which is detrimental to cutting tool performance.
Multi-coloured hues, while attractive, will dissipate upon use and yet the coating will remain fully effective.
nACo offers approximately 4,500 Vickers for impressive solid hardness on cutting areas of the tool, for an increase of up to 2.5 times compared to uncoated bits.

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

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.

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.
