With a 1\/8 inch mill diameter, 0.0150 inch corner radius, and three right-hand spiral flutes, this tool balances chip evacuation with surface finish quality across both roughing and finishing operations. The Zplus PVD coating reduces built-up edge and extends tool life when cutting aluminum and similar materials. At 2.5 inches overall length with a 1\/2 inch length of cut, the 82762 is a compact, single-end centercutting tool suited for CNC machining centers and high-precision toolholders. Licensed machinists and CNC programmers running production or prototype work in aluminum will recognize this as a purpose-built geometry for that material class.\u003c\/p\u003e\n\u003cp\u003eThe 82762 belongs to the H35AL-3 series, which targets aluminum and non-ferrous metals as primary workpiece materials. Secondary material compatibility includes steel, stainless steel, cast iron, high-temperature alloys, and hard materials, though primary performance optimization is for non-ferrous work. The coarse pitch and 35-degree medium helix angle promote aggressive chip flow out of the cut zone, making this tool well-suited for slotting, profiling, and finishing passes on aluminum components in both job shop and production environments. It is specified for use with high-precision toolholders to maintain runout within its rated TIR maximum.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating optimized for aluminum and non-ferrous metals, reducing built-up edge\u003c\/li\u003e\n  \u003cli\u003e0.0150 inch corner radius with a tolerance of -0.0020 to 0.0020 inches for controlled edge blending\u003c\/li\u003e\n  \u003cli\u003e3-flute, right-hand cut, right-hand spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eMaximum TIR of 0.0003 inches supports tight tolerance work when paired with high-precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 82762 is designed for use with high-precision toolholders and is rated for aluminum and non-ferrous metal as primary workpiece materials. Secondary workpiece material codes indicate suitability across steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Straight-cylindrical shank at 1\/8 inch diameter fits standard collet chucks and end mill holders sized for that shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a CNC machinist or toolroom technician. Before mounting, verify the toolholder bore and collet are clean and free of chips or runout-inducing debris. Torque collet nuts according to the toolholder manufacturer specifications. Confirm tool projection and gauge length in the CAM program before cutting to avoid interference and to maintain the rated TIR maximum of 0.0003 inches.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 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\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 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\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 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\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\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\u003eSeries\u003c\/strong\u003e: H35AL-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: 82762\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51728620323122,"sku":"82762","price":56.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/439d4f4f86cd204b1bd849d5cf89664c.jpg?v=1788694057","url":"https:\/\/voomisupply.com\/products\/helical-solutions-82762-corner-radius-end-mill-1-8-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
