Built to the H40ALV-3 series specification, it features a 3\/8-inch diameter, a 1-1\/2-inch length of cut, and a 0.060-inch corner radius. The 40-degree high-helix geometry promotes efficient chip evacuation while reducing cutting forces. A Zplus PVD coating extends tool life across a range of workpiece materials. With a variable pitch design and centercutting capability, this end mill handles full-slot and plunge entry without tool changes. It is sized for straight-cylindrical shank toolholders in CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is primarily suited for aluminum and non-ferrous metals, where the high-helix geometry and Zplus coating deliver clean surface finishes and reduced built-up edge. Secondary applications include steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Typical installation scenarios include production CNC milling, die and mold work, and general-purpose contouring where both roughing and finishing passes are required in a single tool. The long flute length of 1-1\/2 inches supports deep sidewall passes common in aerospace and precision machining applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating optimized for aluminum and non-ferrous materials with secondary capability in steel, stainless, cast iron, and high-temperature alloys\u003c\/li\u003e\n  \u003cli\u003eVariable pitch design reduces harmonic vibration during high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e0.060-inch corner radius with a tight tolerance of -0.0020 to 0.0020 inches reduces stress concentration at part edges\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute with 40-degree high helix for aggressive chip clearance\u003c\/li\u003e\n  \u003cli\u003eRated for use with high-precision toolholders; TIR maximum of 0.0003 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Verify toolholder runout meets or is below the 0.0003-inch TIR maximum before production use to protect the corner radius geometry. Follow the toolholder manufacturer torque specifications when clamping collet nuts or set screws.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees (High Helix)\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\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 Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0003 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\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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: 0.165 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: 48326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51739778810162,"sku":"48326","price":134.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6bc5093dde92525d4bab6e9e3631dba_83dddbed-96de-461b-81fc-c2de9c6888eb.jpg?v=1788818762","url":"https:\/\/voomisupply.com\/products\/helical-solutions-48326-corner-radius-end-mill-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
