It features a 0.5000 inch mill diameter, a 0.6250 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentration at the cutting edge. The three-flute geometry is paired with a variable pitch design and a high helix angle of 40 degrees, promoting chip evacuation and reducing chatter. A Zplus PVD coating extends tool life and improves performance in aluminum and non-ferrous metal applications. The straight cylindrical shank measures 0.5000 inch in diameter, and the overall length is 5.0000 inches. Licensed machinists and CNC tooling professionals install this end mill in high-precision toolholders.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered primarily for aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high temperature alloys, and hard materials. The H40ALV-RN-3 series is classified as a long-length, extended-reach design, with a reach length of 3.3750 inches and a reduced neck diameter of 0.4750 inch that provides clearance in deep-pocket and slotting operations. The centercutting geometry allows plunge entry. It is suited for CNC machining centers running high-speed operations where tight tolerances and surface finish quality are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300 inch corner radius with tolerance of -0.0020 to 0.0020 inch reduces edge chipping on workpiece corners\u003c\/li\u003e\n\u003cli\u003eVariable pitch flute spacing minimizes harmonic chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003e40-degree high helix angle promotes efficient chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eZplus PVD coating provides wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003eExtended reach of 3.3750 inches with 0.4750 inch neck clearance enables deep-pocket milling\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry without pilot drilling\u003c\/li\u003e\n\u003cli\u003eMaximum TIR of 0.0003 inch supports high-precision toolholder applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders.

Ensure the machine spindle and toolholder are clean and free of debris before seating the shank. Verify programmed feed rates and speeds against the workpiece material before initiating the cut. Handle solid carbide tooling carefully to avoid edge chipping from contact with hard surfaces during loading and unloading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.4750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3.3750 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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 Mill Material\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0003 inches\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\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 \/ 0.0620 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High Temperature Alloy, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H40ALV-RN-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.441 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 46371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51730995872050,"sku":"46371","price":203.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a1c47e17775db4fff0d61fda6a9b6a7_ec0adf69-dc16-4338-95c7-e9ee75031b54.jpg?v=1788725592","url":"https:\/\/voomisupply.com\/products\/helical-solutions-46371-corner-radius-end-mill-1-2-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
