Amana tool 51409 CNC SC Spiral O Single Flute Plastic Cutting 1/4 D x 1-1/16 CH x 1/4 SHK x 3 Inch Long Up-Cut Router Bit with Mirror Finish

To be used only on CNC machines and routers with automatic feeding. Solid carbide Spiral 'O' flute Up-Cut plastic cutting CNC router bits use the highest quality sub-micrograin carbide, have a special proprietary edge processing system and feature a super high polished cutting edge with a unique “mirror finish”, resulting in clean cuts, superior surface finish and a longer tool life. The Spiral ‘O’ flute sharpening/finishing process increases feed rates, allowing for more linear feet routed in less time.These bits are specifically designed for a variety CNC machining applications and a long list (see below) of materials. Continuous improvements in cutting performance, the unique carbide polishing process, tool design & geometry make these router bits perfect for routing signs and displays. Signmaking (signcrafter) router bits were originally developed in Europe specifically for professional sign makers. Corrugated plastic products, such as Correx boards are used in a variety of applications including boat building, packaging, signage, outdoor advertising, and the production of pet cages. Today, CNC routers have become the tool of choice for sign makers, moving beyond printers and vinyl cutters.Benefits of Mirror-Finish:Industrial qualitySingle flute designSuper high flute mirror finish results in better cut qualityDissipates heat well and prevents meltingRight hand helix/right hand cutEject chips up or downLonger tool lifeSolid carbide Spiral ‘O’ flute plastic cutting router bits produce super-clean cuts in the following materials:Plastic/Acrylic  Acetal and NylonAcrylic StoneAcrylonitrile Butadiene Styrene (ABS)Aluminum Composite Material (ACM)AlupanelCorianCoroplast *Corrugated Plastics such as Correx Boards and PolypropolyeneCrosslinked Polyethylene (XPE, PEX, XLPE)DerlinDibondExtruded AcrylicFoam BoardFomexGatorfoam **Hard PlasticHigh Density Polyethylene (HDPE)High Density Urethane (HDU Board)High Impact Polystyrene (HIPS)High Impact Polystyrene (HIPS) for digital printingHigh Pressure Laminates (HPL)Hydroxy-Terminated Polyether (HTPE)King ColorCore ***LaminateLow Density Polyethylene (LDPE)LubXLuciteMechanical / Engineered PlasticsPerspex Cast Acrylic SheetPlexiglasPoly (methyl methacrylate) (PMMA)Polycarbonate (Lexan™)Polyethylene Terephthalate Glycol-Modified (PETG / PET-G)Polyoxymethylene (POM), also known as Acetal, Polyacetal and PolyformaldehydePolystyrene (PS)PVCSign FoamSintra PVCSolid SurfacesStarBoard (King StarBoard 'R') High Density Polyethylene Sheet (HDPE)TeflonThermoplastic Polyolefin (TPO)Trespa Meteon****Ultra High Molecular Weight Polyethylene (UHMWPE)UrethaneVinyl FlooringWood* Coroplast is 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. *** King ColorCore, The Multi-Color Engravable Polymer Sheet. **** Decorative high-pressure compact laminate (HPL) with an integral surface. ATTENTION! 51415 reduce RPM & Feed Rates (IPM) by 30-50% to prevent tool breakage due to extremely small diameter (D). These bits are high finish (not mirror finish due to small diameter).
