It features a 3\/16 inch (0.1875 inch) shank diameter, a 0.625 inch mill diameter, and a 1 inch length of cut. The tool carries a ZrN (zirconium nitride) PVD coating applied through PROMAX PowerLayer technology, which improves surface hardness and lubricity for extended tool life. With three flutes, a variable helix, and a coarse pitch, the US362016 is optimized for roughing operations. It is a single-end, center-cutting tool with right-hand flute direction and right-hand cutting direction. Machinists and tool-and-die professionals specify this end mill for precision work on aluminum, copper, brass, and other non-ferrous workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThe US362016 belongs to the PROMAX Series US362 short-length corner radius end mill line. It is suited for milling operations in CNC machining centers and manual mills where a controlled corner radius of 0.015 inch is required to reduce stress concentrations in pocket floors and shoulder features. Its short length-type geometry provides rigidity during aggressive roughing passes in non-ferrous metal components. The straight-cylindrical shank is compatible with standard collet chucks and toolholders used in professional machine shops handling production or prototype work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eZrN PVD coating reduces friction and extends tool life on aluminum and other non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eVariable helix design minimizes chatter and improves chip evacuation during roughing cuts\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius (tolerance: -0.0010 to 0.0010 inch) reduces stress risers at pocket corners\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch, 3-flute layout balances chip load and material removal rate on softer non-ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard collet-style toolholders accepting a 3\/16 inch straight-cylindrical shank. Optimized for non-ferrous metal workpiece materials including aluminum, brass, copper, and similar alloys (Primary Workpiece Material Code: N per supplier data).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a compatible collet chuck or end mill holder, ensuring the shank is fully seated and the collet is torqued to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates corner radius wear. Coolant-through is not supported on this tool; apply flood or mist coolant externally when cutting non-ferrous materials to manage heat and chip evacuation. Do not use this tool on ferrous materials, as the ZrN coating is optimized for non-ferrous applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (0.5000 inch decimal per spec sheet)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0010 to 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride) PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: US362\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: US362016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51974450381106,"sku":"US362016","price":71.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c9c8ed5d3fb5ae7a21a9f1da388a903_3734c8b8-b1e9-42ad-a3c1-251784d2e1e3.jpg?v=1789977376","url":"https:\/\/voomisupply.com\/products\/promax-us362016-corner-radius-end-mill-3-16-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
