Amana tool 51870-Z CNC Square End Mil, Aluminum Cutting 1/2 D x 1-1/4 CH x 1/2 SHK x 3 Inch Long x 3 Flute SC ZrN Coated Up-Cut Router Bit

To be used only on CNC machines and routers with automatic feeding. Produce super clean and extra smooth finish cuts in Aluminum and non-Ferrous metals. Solid carbide industrial 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. 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: AluminumAluminum 5052Aluminum 6061BrassCopper Gold Non-Ferrous MetalsSilver WARNING! 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.
