Amana 3/16Dx1/4SHK DWCUT PLASTIC SPK 51517-K

Leaves an Extra High Surface FinishThose seeking improved surface finishes in either plastic, woods and other materials would do well by using Amana ToolA‚A®'s 3 flute, Low Helix Finishers. The unbeatable combination of three keen edges and a gentle 10A‚A° helix equates to a stiffer tool that minimizes both part movement and edge burring, leaving a smooth finish.Low Helix Up-Cut and Down-CutLeaves an Extra High Surface Finish3 Flute (unless noted otherwise, item #51734-K is 2-flute)Excellent for Cutting:PlasticAcrylic StoneAcrylonitrile Butadiene Styrene (ABS)CorianComposite PlasticCoroplastA‚A®*DelrinA‚A®FoamFomexA‚A®HardwoodHigh Impact Polystyrene (HIPS)High Pressure Laminates (HPL)Hydroxy-Terminated Polyether (HTPE)Low Density Polyethylene (LDPE)LubXA‚A®PerspexA‚A® Cast Acrylic SheetPoly (methyl methacrylate) (PMMA)Polyethylene Terephthalate Glycol-Modified (PETG / PET-G)Polyoxymethylene (POM), also known as Acetal, Polyacetal and PolyformaldehydePrecision BoardSign FoamSoftwoodSolid SurfaceStarBoardA‚A® (King StarBoard 'R') High Density Polyethylene Sheet (HDPE)Thermoplastic Polyolefin (TPO)Urethane*CoroplastA‚A® is soft plastic cardboard made with super soft, super flexible PVC.SpektraA bits feature a nACoA‚A® 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 which 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. nACoA‚A® nanocomposite coating will not wear off.
