It features a 1\/4 inch mill diameter, 3\/4 inch length of cut, and a 0.0600 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life. The 3-flute, right-hand spiral geometry with variable pitch (Series H40ALV-3) helps break up harmonics and chatter during aggressive cuts. This single-end, centercutting design handles both plunge and contour operations, making it a practical choice for machinists running aluminum aerospace components, housings, and general non-ferrous workpieces.\u003c\/p\u003e\n\u003cp\u003eThis end mill is primarily suited for aluminum and non-ferrous metal machining but is also capable across steel, stainless steel, cast iron, high-temperature alloys, and hard materials as secondary workpiece materials. The bright\/uncoated finish is appropriate for aluminum applications where coatings can cause built-up edge. It is designed for use with high-precision toolholders to maintain the 0.0003 inch maximum TIR and h6 shank tolerance. Typical installation environments include CNC machining centers running production or prototype work where chatter suppression and surface finish quality are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0600 inch corner radius with a tight tolerance of -0.0020 to 0.0020 inch for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eVariable pitch design suppresses chatter and harmonics during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e3-flute solid carbide construction balances chip evacuation and rigidity\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003e40 degree high helix angle promotes efficient chip flow in aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish prevents built-up edge when machining aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Seat the 1\/4 inch straight-cylindrical shank fully and evenly in a high-precision toolholder to maintain runout within the 0.0003 inch TIR maximum. Verify spindle and toolholder cleanliness before clamping, and confirm correct tool stick-out for the intended operation. Always reference the machine tool manufacturer guidelines and applicable shop safety procedures before beginning setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 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: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 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\u003eSeries\u003c\/strong\u003e: H40ALV-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.053 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: 48130\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51739808235826,"sku":"48130","price":61.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6bc5093dde92525d4bab6e9e3631dba_2560f8cf-0d5f-4678-b532-a41b7acd1cbd.jpg?v=1788819077","url":"https:\/\/voomisupply.com\/products\/helical-solutions-48130-corner-radius-end-mill-1-4-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
