It features a 1\/2-inch diameter, a 1-1\/4-inch length of cut, and a 0.03-inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The Tplus PVD coating provides enhanced wear resistance and heat dissipation. With a variable index pitch and right-hand helical flutes, this tool is engineered for both roughing and finishing operations in a single setup. It is installed and operated by machinists and CNC programmers in precision machine shops.\u003c\/p\u003e\n\u003cp\u003eThis end mill is optimized for primary use in stainless steel, superalloys, and titanium, with secondary application capability in non-ferrous metals and hard materials. The centercutting geometry allows plunge entry, and the straight-cylindrical shank is compatible with high-precision toolholders. The regular-length flute configuration suits general-purpose milling, slotting, profiling, and contouring in vertical and horizontal machining centers. It is part of the HEV-5 series, which is purpose-built for difficult-to-machine workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-flute variable index geometry reduces harmonic vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eTplus PVD coating enhances wear resistance in stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius reduces edge chipping and improves surface finish at part radii\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003eRight-hand helical flutes with right-hand cutting direction for standard spindle use\u003c\/li\u003e\n  \u003cli\u003eCapable of roughing and finishing in a single tool, reducing changeover time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Ensure the machine spindle is fully stopped and the tool path program is verified before securing the shank in the toolholder. Use a high-precision collet or hydraulic toolholder to maintain TIR within the specified maximum of 0.0005 inches. Follow the cutting tool manufacturer feed-and-speed recommendations for the specific workpiece material to avoid premature coating wear or edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Tplus (PVD)\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: Helical\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\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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 and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 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: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 to 0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HEV-5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 59877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51728098820402,"sku":"59877","price":183.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/158f2309d2a95a0e47e66a3f43ce42b8_b1760241-f0aa-488b-815d-f609ea05c5ed.jpg?v=1788687932","url":"https:\/\/voomisupply.com\/products\/helical-solutions-59877-corner-radius-end-mill-1-2-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
