Amana Tool 51505 CNC SC Spiral O Single Flute, Plastic Cutting 1/4 D x 1 CH x 1/4 SHK x 2-1/2 Inch Long Down-Cut Router Bit with Mirror Finish

To be used only on CNC machines and routers with automatic feeding. Solid carbide down-cut spiral 'O' flute plastic cutting 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 quality Single flute design Super high flute mirror finish results in better cut quality Dissipates heat well and prevents melting Right hand helix/right hand cut Eject chips up or down Longer tool lifeSolid carbide Spiral O flute plastic cutting router bits produce super-clean cuts in the following materials: Plastic/Acrylic Acetal and Nylon Acrylic Stone Acrylonitrile Butadiene Styrene (ABS) Aluminum Composite Material (ACM) Alupanel Corian Coroplast* CorrugatedPlasticssuch as Correx Boards and Polypropolyene Derlin 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 Hydroxy-Terminated Polyether (HTPE) King ColorCore*** Laminate Low Density Polyethylene (LDPE) LubX Lucite Mechanical / Engineered Plastics Plexiglas Poly (methyl methacrylate) (PMMA) Polycarbonate (Lexan) Polyethylene Terephthalate Glycol-Modified (PETG / PET-G) Polyoxymethylene (POM), also known as Acetal, polyacetal, and polyformaldehyde Polystyrene (PS) PVC Sign Foam Sintra PVC Solid Surfaces StarBoard (King StarBoard 'R') High Density Polyethylene Sheet (HDPE) Teflon Thermoplastic Polyolefin (TPO) Trespa Meteon**** Ultra High Molecular Weight Polyethylene (UHMWPE) Urethane Wood* 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 and 51515 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). Maximum RPM: 35,000
