It features a 3\/16 inch (0.1875 inch) mill diameter, a 0.0100 inch corner radius, and a 0.7500 inch length of cut. The Zplus PVD coating optimizes performance in aluminum and non-ferrous metals while also handling steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The variable pitch, right-hand helical flute geometry helps reduce chatter and improve chip evacuation. This tool is sized for high-precision toolholders and is used by machinists and CNC tool-and-die professionals in production environments.\u003c\/p\u003e\n\u003cp\u003eThe 86101 belongs to HELICAL SOLUTIONS Series H40ALV-3, a line built for demanding multi-material applications. Its primary application is aluminum and non-ferrous metals, with secondary capability across steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The centercutting geometry allows plunge entry, making it suitable for slotting, profiling, and pocketing operations in precision machined components. A straight-cylindrical shank and 2.5 inch overall length make it compatible with standard high-precision collet and shrink-fit toolholder setups used in CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-flute solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating optimized for aluminum and non-ferrous metals with multi-material capability\u003c\/li\u003e\n  \u003cli\u003eVariable pitch design reduces harmonic vibration and chatter during cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting end allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e0.0100 inch corner radius extends tool life and reduces edge chipping at part corners\u003c\/li\u003e\n  \u003cli\u003eMaximum TIR of 0.0003 inch for high-precision, tight-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders including collet chucks and shrink-fit holders.

Ensure the machine spindle and toolholder are fully de-energized and at rest before inserting or removing the end mill. Seat the shank fully in the toolholder bore and verify runout does not exceed the 0.0003 inch TIR maximum before production cutting. Consult the toolholder manufacturer's clamping torque specifications and follow shop SOP for speeds, feeds, and coolant strategy appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 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\u003eCorner Radius\u003c\/strong\u003e: 0.0100 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: 0.1875 inches (3\/16 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 Type\u003c\/strong\u003e: Corner Radius, Centercutting\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\u003eFlute Type\u003c\/strong\u003e: Helical\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\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\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 to 0.0620 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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 86101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51741149397298,"sku":"86101","price":70.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c1b1ad8edbe24171df8078052f1b268_466ee20b-6978-4d8b-b96b-2d46bdd9f8fa.jpg?v=1788829629","url":"https:\/\/voomisupply.com\/products\/helical-solutions-86101-corner-radius-end-mill-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
