Amana Tool AMS-141 1/4" 4 Piece CNC Ball Nose and Flat Bottom Router Bit Set

Specially designed for 2D and 3D CNC profiling and carving in plastic, aluminum and wood with CNC machines. The high-shear ball nose tips cut smooth 2D and 3D contours with reduced stepping while the proprietary ZrN 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 we 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 high balance that allows them to run up to 60,000 RPMs. Adjust our chip load and feed rate accordingly.

*A soft plastic cardboard made with super soft, super flexible PVC.
**Expanded polypropylene (EPP) is a foam form of polypropylene.
***Ethafoam, Polyethylene, and Polylam are durable, flexible, closed-cell foams with excellent memory.

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.
