Amana tool 51777-Z CNC SC Spiral O Single Flute, Aluminum Cutting 1/8 D x 5/16 CH x 1/4 SHK x 1-1/2 Inch Long Down-Cut ZrN Coated Router Bit with Mirror Finish

To be used only on CNC machines and routers with automatic feeding. Solid carbide spiral 'O' flute aluminum cutting ZrN coated 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, less chance for chip re-welding, a 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.Benefits of ZrN Coating:Creates incredibly precise detail workOptimized flute geometry and low Total Indicated Runout (TIR) guarantees clean cuts, essentially eliminates sanding and reduces chatter when used with low TIR spindlesCreates a harder and tougher cutting ceramic over carbide edge, allowing for a prolonged cutting edge life and helps to prevent the build-up/galling of material in the flutes while cuttingPVD ceramic hardcoat designed for soft, gummy and abrasive materialsHigh aspect ratio for single pass deep-reach cuttingHigh flute volume supports high feed rates and chip loads. Has the ability to run and/or be spun much faster than uncoated toolsFlute geometry optimized for cutting sign foam, sign board, hardwoods, thermoplastics and phenolic compositesExcellent for cutting:ALPOLIC Copper Composite Material (CCM)AlucobondAluminumAluminum 5052Aluminum 6061Aluminum Alloys (Al-Alloy)Aluminum Composite Materials (ACM)Aluminum Composite Panel (ACP)AlupanelBrassCopperDibondDurabond*e-panel™EtalbondFomex with Aluminum FaceGoldNon-Ferrous MetalsPlasticSilverSolid SurfaceTitanium Composite Material (TCM)Wood*Durabond is a polyethylene core with 0.3mm colored aluminum sheet on either side. It is a pre-finished product that requires no decoration.These router bits are specifically designed for a variety CNC machining applications. 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. Today, CNC routers have become the tool of choice for sign makers, moving beyond printers and vinyl cutters.Industrial qualitySingle flute designSuper high flute mirror finish results in better cut qualityDissipates heat well and prevents meltingRight hand helix/right hand cutEject chips upLonger tool lifeMaximum RPM: 35,000WARNING! Never attempt to cut ferrous metals with these bits. Inspect cut quality and adjust feed / speed accordingly. For optimal results and extended tool life use mist lubricant system or air cooling.
