Built to the H40ALV-3 series specification, it features a 3\/8-inch diameter, a 1-inch length of cut, and a Zplus PVD coating optimized for aluminum and non-ferrous metals as the primary workpiece material. The 0.060-inch corner radius reduces stress concentration at the cutting edge, extending tool life in both roughing and finishing operations. Variable pitch geometry and a high helix style work together to reduce harmonic vibration and improve chip evacuation in demanding cuts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision machining environments where both surface finish and material removal rate matter. It handles aluminum and non-ferrous metals as primary applications and is rated for secondary use in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The single-end, centercutting design allows plunge entry and full slot cuts. It is intended for use with high-precision toolholders to maintain runout within the stated TIR of 0.0003 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZplus PVD coating rated for aluminum and non-ferrous primary applications with secondary capability in steel, stainless, cast iron, high-temp alloys, and hard materials\u003c\/li\u003e\n  \u003cli\u003e0.060-inch corner radius with a tight tolerance of -0.002 to +0.002 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003e3-flute, variable pitch design reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eHigh helix style promotes efficient chip evacuation, critical in aluminum and gummy materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction with h6 shank and mill diameter tolerances for accurate toolholder fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders. Mill diameter and shank diameter both hold h6 tolerance at 3\/8 inch, making this end mill compatible with collet chucks, hydraulic chucks, and shrink-fit holders machined to that standard. Refer to toolholder manufacturer specifications to confirm bore tolerance match.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Seat the straight-cylindrical shank fully into a high-precision toolholder and torque the retention mechanism to the toolholder manufacturer specification before spindle operation. Verify runout at the cutting edge does not exceed the stated TIR maximum of 0.0003 inches using a dial indicator before production cuts. Do not exceed the rated length of cut or apply side loads beyond the tool geometry limits, as solid carbide end mills are brittle and can fracture under excessive deflection.\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 inch (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 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inches\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\u003eHelix Style\u003c\/strong\u003e: High (40 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Variable\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\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\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\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\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.062 \/ +0.062 inches\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\u003eExtended Reach\u003c\/strong\u003e: No\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: 0.112 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 48276\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51736341414194,"sku":"48276","price":90.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c1b1ad8edbe24171df8078052f1b268_df59ce48-9b60-4785-a518-590c53c232eb.jpg?v=1788777327","url":"https:\/\/voomisupply.com\/products\/helical-solutions-48276-corner-radius-end-mill-3-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
