It features a 3\/16-inch (0.1875 inch) shank and mill diameter, a 1.625-inch length of cut, and a 0.030-inch corner radius that reduces stress concentration at the cutting edge. The ZrN (zirconium nitride) PVD coating improves surface hardness and wear resistance without adding significant heat. With three flutes, a variable helix, and a coarse pitch, this tool is optimized for roughing passes. It is a single-end, right-hand cutting tool intended for use in compatible straight-shank toolholders.\u003c\/p\u003e\n\u003cp\u003eThe US362018 is suited for machining non-ferrous metals including aluminum alloys, copper, brass, and similar materials. It fits standard toolholder setups on CNC milling machines and manual mills where a stub-length, straight-cylindrical shank is required. The variable helix geometry helps reduce chatter during aggressive roughing cuts, making it a practical choice for production environments and job shops working with softer, gummy, or high-chip-volume materials where controlled chip evacuation matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin construction for rigidity and edge retention in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eZrN PVD coating provides enhanced wear resistance and reduced built-up edge on non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable helix geometry reduces harmonic chatter during roughing cuts\u003c\/li\u003e\n  \u003cli\u003e0.030-inch corner radius protects the cutting edge and improves corner strength in pocketing and profiling\u003c\/li\u003e\n  \u003cli\u003eThree-flute, coarse-pitch design promotes chip evacuation during high material-removal-rate operations\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank toolholders accepting a 3\/16-inch shank diameter.

Ensure the toolholder collet or chuck is clean and within spec before seating the shank to maintain runout tolerances. Confirm shank engagement depth meets the toolholder manufacturer minimum before tightening. Reference the machine tool manufacturer guidelines and applicable shop safety procedures when setting speeds and feeds for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (1.0000 inch decimal per series spec  -  see note: raw data lists decimal as 1.0000; shank diameter is 0.1875 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inch (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 inch\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\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\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\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\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: US362018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52064083902770,"sku":"US362018","price":73.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c9c8ed5d3fb5ae7a21a9f1da388a903_e9447e6a-5694-4344-a2bf-d50c2a5b76c4.jpg?v=1790043795","url":"https:\/\/voomisupply.com\/products\/promax-us362018-corner-radius-end-mill-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
