Built to a 0.1562 inch (5\/32 inch) cutting diameter with a 0.03 inch corner radius and a long-flute length of cut measuring 0.5000 inches, this tool is part of the Miniature End Mills - Corner Radius - Long Flute series. The four-flute, right-hand cutting geometry combined with an AlTiN PVD coating makes it well-suited for finishing operations in steel, stainless steel, cast iron, and non-ferrous metals. A 30-degree helical flute profile promotes smooth chip evacuation and surface finish quality in tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for CNC machining centers and milling machines where miniature tooling is required. Its long-flute configuration provides extended reach into pockets, slots, and contoured features without sacrificing rigidity typical of solid carbide construction. The straight cylindrical shank with a 0.1875 inch (3\/16 inch) diameter is compatible with standard collet-style and precision toolholders. Finishing passes on steel, stainless steel, cast iron, and non-ferrous or composite workpiece materials are the primary application. No coolant-through capability is present on this tool, so external coolant or air blast is used when required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN PVD coating for elevated heat resistance and tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius with a tight tolerance of plus or minus 0.0010 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eFour-flute, right-hand helical design suited for finishing-grade material removal\u003c\/li\u003e\n  \u003cli\u003eLong-flute length of cut at 0.5000 inches provides extended reach in miniature milling operations\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry where the application requires it\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction maintains rigidity and dimensional stability at small diameters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard collet-style toolholders and precision milling toolholders accepting a 0.1875 inch straight cylindrical shank.

The straight shank must be seated to proper insertion depth in the toolholder and torqued according to the toolholder manufacturer specifications. Runout should be checked at setup, as miniature-diameter tools are sensitive to collet contamination and improper seating. Verify the toolholder bore is clean and free of chips before securing the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1562 inches (5\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.0010 to minus 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to minus 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.0100 to minus 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.03 inches L x 0.32 inches W x 0.32 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 830930-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51737328714034,"sku":"830930-C3","price":77.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5c3b65b5c070898e93f5424f0d48634_caa43548-ce8d-4ab6-bf54-1e3c5c0be72a.jpg?v=1788787156","url":"https:\/\/voomisupply.com\/products\/harvey-tool-830930-c3-corner-radius-end-mill-0-1562in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
