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. Left hand helix left hand cut. Excellent for cutting: Plastic/Acrylic Acetal and Nylon Acrylic Stone Acrylonitrile Butadiene Styrene (ABS) Aluminum Composite Material (ACM) Alupanel® Corian Coroplast® ** Corrugated Plastics such as Correx Boards and Polypropylene * Crosslinked Polyethylene (XPE, PEX, XLPE) Delrin Dibond® Extruded Acrylic Foam Board Fomex® Gatorfoam® *** Hard Plastic High Density Polyethylene (HDPE) High Density Urethane (HDU Board) High Impact Polystyrene (HIPS) High Impact Polystyrene (HIPS) for digital printing High Pressure Laminates (HPL) Hydroxy-Terminated Polyether (HTPE) King ColorCore® The Multi-Color Engravable Polymer Sheet. Laminate Low Density Polyethylene (LDPE) LubX® Lucite® Mechanical/Engineered Plastics Perspex® Cast Acrylic Sheet Plexiglas® Poly (methyl methacrylate) (PMMA) Polycarbonate (Lexan™) † Polyethylene Terephthalate Glycol-Modified (PETG / PET-G) Polyoxymethylene (POM), also known as Acetal, Polyacetal and Polyformaldehyde.

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™.

Benefits of Mirror-Finish:

Razor sharp cutting edge Effortless chip removal Helps prevent chip re-welding Extends tool life

Exceptional cut quality Dissipates heat well and prevents melting 35,000. Maximum RPM:
