Edge of Arlington offers free shipping in the United States when you choose flat rate shipping.

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.  Ideal for industrial applications and CNC machines. Right hand helix; right hand cut. Benefits of Mirror-Finish: Razor sharp cutting edge, effortless chip removal, helps prevent chip re-welding.

Excellent for cutting: Plastic/Acrylic, Acetal and Nylon, Acrylic Stone, Acrylonitrile Butadiene Styrene (ABS), Alupanel®, Corian, Coroplast®**, Corrugated Plastics* such as Correx Boards and Polypropylene, Delrin, Foam Board, Gatorfoam®***, High Density Polyethylene (HDPE), High Impact Polystyrene (HIPS), High Impact Polystyrene (HIPS) for digital printing, King ColorCore® The Multi-Color Engravable Polymer Sheet, Laminate, Lucite®, Low Density Polyethylene (LDPE), Mechanical/Engineered Plastics, Plexiglas®, Poly (methyl methacrylate) (PMMA), Polycarbonate, Polyethylene Terephthalate Glycol-Modified (PETG / PET-G), PVC, Sintra PVC, Solid Surface, Teflon®, Thermoplastic Polyolefin (TPO), Ultra High Molecular Weight Polyethylene (UHMW), Wood.

*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.

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 that enables the tool's 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.
