It features a 1\/2 inch diameter, a 0.0300 inch corner radius, and three flutes with a variable pitch and high-helix geometry. The Zplus PVD coating improves wear resistance and chip evacuation, particularly in non-ferrous and aluminum applications. Extended reach geometry with a 2-3\/4 inch reach length and a reduced 0.4750 inch neck diameter allows access to deeper features without sacrificing rigidity. This tool is intended for use in CNC machining centers by skilled machinists and toolroom professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling aluminum, non-ferrous metals, steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The corner radius configuration reduces stress concentrations at the cutting edge, extending tool life in both slotting and profiling passes. The single-end, centercutting design supports plunge entry. It is optimized for use with high-precision toolholders and performs best in applications that demand consistent edge geometry and tight tolerances. Series H40ALV-RN-3 identifies this tool within the HELICAL SOLUTIONS extended-reach variable-index family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with Zplus PVD coating for extended wear life in aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable pitch flutes reduce harmonic vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e0.0300 inch corner radius with a tight tolerance of -0.0020 to 0.0020 inch\u003c\/li\u003e\n  \u003cli\u003eExtended reach design: 2-3\/4 inch reach length with 0.4750 inch neck diameter\u003c\/li\u003e\n  \u003cli\u003eCentercutting, single-end configuration supports plunge milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute direction; suitable for roughing and finishing in one tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders in CNC machining applications.

Seat the 1\/2 inch straight-cylindrical shank fully into a high-precision toolholder and verify runout does not exceed the 0.0003 inch TIR maximum before cutting. Confirm spindle direction matches the right-hand cutting configuration before initiating any toolpath. Do not exceed the recommended reach depth for the neck diameter, as excessive lateral force on the neck can cause tool deflection or breakage.\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 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 inches (4.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.4750 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-3\/4 inches (2.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Variable\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Zplus (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0003 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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\u003eSeries\u003c\/strong\u003e: H40ALV-RN-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.395 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: 81514\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51730660131122,"sku":"81514","price":181.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/836188df6fd5041e7ae08acb61863f8a_20c0a13c-b820-4404-81c4-0e1f82de33f5.jpg?v=1788721020","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81514-corner-radius-end-mill-1-2-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
