To be used only on CNC machines and routers with automatic feeding.
Produce super clean, smooth cuts especially in acrylic materials (Plexiglas® Lucite®) other plastics and wood. Bits are made according to strict tolerances from an exclusive carbide grade and polished to a mirror finish using Amana’s unique process. Designed to eject chips up. Ideal for industrial applications and CNC machines. Right hand helix right hand cut.

*Corrugated Plastics such as Correx refers to a wide range of extruded twinwall plastic-sheet products produced from high-impact Polypropylene resin with a similar make-up to corrugated fiberboard. They are used in a variety of applications including boat building packaging signage outdoor advertising and the production of pet cages.
**A soft plastic cardboard made with super soft super flexible PVC.
***Gatorfoam® Foam Board a polystyrene foam board bonded between two layers of Luxcell® wood-fiber veneer.
****Decorative high-pressure compact laminate (HPL) with an integral surface.
†Recommendation: Use the slowest suggested feed rates and the shortest bits necessary for cutting and routing Lexan™.
