It features a 0.1250 inch mill diameter, a 0.0300 inch corner radius, and three helical flutes with a variable pitch and variable index geometry. The Zplus PVD coating improves lubricity and wear resistance, making this tool well-suited for aluminum and other non-ferrous metals. At 2.5 inches overall length with a 0.5000 inch length of cut, it is a compact, rigid tool built for precision work in tight setups. Maximum TIR is held to 0.0003 inches.\u003c\/p\u003e\n\u003cp\u003eThis end mill is primarily intended for machining aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high temperature alloys, and hard materials. It is a single-end, center-cutting tool with right-hand flute direction and right-hand cutting direction, making it compatible with standard CNC milling setups. The Series H40ALV-3 designation places it in Helical Solutions' aluminum-optimized line. It is recommended for use with high-precision toolholders to maintain runout tolerances. Typical users include CNC machinists and tool-and-die professionals working in production or prototype environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0300 inch corner radius with tolerance of -0.0020 to 0.0020 inches for controlled blending at part corners\u003c\/li\u003e\n  \u003cli\u003eVariable pitch, variable index geometry reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating optimized for aluminum and non-ferrous machining\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eHigh helix style promotes efficient chip evacuation in gummy materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders in CNC milling applications.

Seat the straight-cylindrical shank fully into a high-precision toolholder and torque the collet or set screw per the toolholder manufacturer's specification. Verify runout at the cutting edge before initiating a cut, as TIR maximum is 0.0003 inches. Do not exceed the rated length of cut of 0.5000 inches when programming axial depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 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: 0.5000 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: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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 to 0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0003 inches\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\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-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 81424\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51742662426930,"sku":"81424","price":67.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c1b1ad8edbe24171df8078052f1b268_4f7eb903-ac18-4376-af6e-2f06c583f7bb.jpg?v=1788838672","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81424-corner-radius-end-mill-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
