It carries a 0.5-inch mill diameter, a 1.625-inch length of cut, and a 0.015-inch corner radius that reduces edge chipping and extends tool life at the cutting corner. The three-flute, right-hand helical geometry uses a variable pitch design to suppress harmonic vibration during aggressive cuts, making it well suited for both roughing and finishing passes in a single setup. The 40-degree high helix angle promotes chip evacuation in deep-pocket and slot milling applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for CNC machining centers running aluminum, copper, brass, and similar non-ferrous workpiece materials as its primary application. It is part of the H40ALV-3 series, which targets high-speed aluminum machining where chip load consistency and surface finish quality matter. Secondary workpiece materials include steel, stainless steel, cast iron, high-temperature alloys, and hard materials, though aluminum and non-ferrous metals are the rated primary targets. The tool is center-cutting, allowing direct plunge entry. A high-precision toolholder is recommended for maintaining runout within the 0.0003-inch TIR maximum specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and thermal resistance in high-speed cuts\u003c\/li\u003e\n  \u003cli\u003e0.015-inch corner radius reduces stress concentration and edge breakout on part corners\u003c\/li\u003e\n  \u003cli\u003eVariable pitch fluting reduces chatter and harmonic vibration without requiring variable helix\u003c\/li\u003e\n  \u003cli\u003e40-degree high helix angle promotes rapid chip evacuation in aluminum pocketing and slotting\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eUncoated substrate optimized for non-ferrous metals where coatings can cause built-up edge\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the HELICAL SOLUTIONS H40ALV-3 series.

Seat the 0.5-inch straight-cylindrical shank fully into a high-precision collet or toolholder and verify runout does not exceed the 0.0003-inch TIR maximum before running at speed. Confirm spindle direction is set to right-hand rotation to match the cutting direction. Follow machine tool manufacturer guidelines for clamping torque and axial tool projection to avoid deflection during extended-reach operations.\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\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Medium\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: Aluminum, Non-Ferrous Metal\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.002 to 0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.062 to 0.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H40ALV-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: 0.328 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: 48430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51743340233010,"sku":"48430","price":136.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6bc5093dde92525d4bab6e9e3631dba_676e8546-dedf-455c-b727-cd95b49dc74f.jpg?v=1788845856","url":"https:\/\/voomisupply.com\/products\/helical-solutions-48430-corner-radius-end-mill-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
