It carries a 0.5-inch mill diameter with a 0.0300-inch corner radius and features 3 flutes with a variable-pitch, high-helix geometry. The 6-inch overall length and 4.25-inch reach make it well suited for deep-cavity and extended-reach cutting applications. Center-cutting capability allows direct plunging into the workpiece. Manufactured to h6 shank and diameter tolerances, with a TIR maximum of 0.0003 inches, this end mill delivers consistent dimensional accuracy across production runs.\u003c\/p\u003e\n\u003cp\u003eThe 46400 is engineered primarily for aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Its extra-long length and 0.475-inch neck diameter make it a practical choice for deep-pocket profiling and contouring where standard-length tooling cannot reach. The Series H40ALV-RN-3 designation identifies it within HELICAL SOLUTIONS extended-reach, variable-index product family. This end mill is intended for use with high-precision toolholders and is appropriate for CNC machining centers operating at elevated surface footage on non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003e0.0300-inch corner radius with tolerance of -0.0020 to +0.0020 inches reduces stress concentration at cutting corners\u003c\/li\u003e\n  \u003cli\u003eVariable-pitch flutes (variable index) reduce harmonic chatter during aggressive material removal\u003c\/li\u003e\n  \u003cli\u003eExtra-long 6-inch OAL with 4.25-inch reach for deep-cavity and extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design permits direct ramp or plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish optimized for aluminum and non-ferrous materials where coating buildup is a concern\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute direction; compatible with high-precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders on CNC machining centers.

Seat the 0.5-inch straight-cylindrical shank fully into a high-precision toolholder and confirm runout does not exceed the 0.0003-inch TIR maximum before beginning a cut. Inspect the corner radius and flute edges for chipping during each tool change. Follow the machine and toolholder manufacturer guidelines for pull-stud torque and retention force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.475 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 4.25 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 (Variable Index)\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: Extra Long\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eExtended Reach\u003c\/strong\u003e: Yes\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\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\u003eWeight\u003c\/strong\u003e: 0.534 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: 46400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51742850285874,"sku":"46400","price":188.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/158f2309d2a95a0e47e66a3f43ce42b8_4f912b03-586c-408f-9fec-cf7578e04548.jpg?v=1788839815","url":"https:\/\/voomisupply.com\/products\/helical-solutions-46400-corner-radius-end-mill-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
