Leaves an Extra High Surface Finish Those seeking improved surface finishes in either plastic, woods and other materials would do well by using Amana Tool's 3 flute, Low Helix Finishers. The unbeatable combination of three keen edges and a gentle 10? helix equates to a stiffer tool that minimizes both part movement and edge burring, leaving a smooth finish.  3 FluteLow Helix Up-Cut and Down-CutLeaves an Extra High Surface FinishExcellent for Cutting: PlasticAcrylic StoneAcrylonitrile Butadiene Styrene (ABS)CorianComposite PlasticCoroplast*DelrinFoamFomexHardwoodHigh Impact Polystyrene (HIPS)High Pressure Laminates (HPL)Hydroxy-Terminated Polyether (HTPE)Low Density Polyethylene (LDPE)LubXPerspex Cast Acrylic SheetPoly (methyl methacrylate) (PMMA)Polyethylene Terephthalate Glycol-Modified (PETG / PET-G)Polyoxymethylene (POM), also known as Acetal, Polyacetal and PolyformaldehydePrecision BoardSign FoamSoftwoodSolid SurfaceStarBoard (King StarBoard 'R') High Density Polyethylene Sheet (HDPE)Thermoplastic Polyolefin (TPO)Urethane*Coroplast is soft plastic cardboard made with super soft, super flexible PVC.
