It carries a 1\/2-inch cutting diameter with a 5\/8-inch length of cut and runs a 40-degree high-helix geometry to promote efficient chip evacuation in gummy, low-iron alloys. The Zplus PVD coating adds surface hardness and lubricity to extend tool life in high-speed aluminum applications. The reduced neck and variable index flute spacing work together to reduce chatter and improve finish quality in deep-pocket and wall-milling scenarios. Licensed machinists and CNC programmers working in job shops or aerospace component manufacturing will find this tool sized and coated for high-throughput aluminum work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for non-ferrous metal cutting, with a primary focus on aluminum alloys. The reduced neck profile and 1-3\/4-inch reach length make it well suited for deep-pocket milling and slotting where a standard-length tool would interfere with the part or fixture. The single-end, right-hand cutting and flute direction configuration is compatible with conventional vertical and horizontal CNC machining centers. The straight cylindrical shank accepts standard ER or milling chuck toolholders sized for 1\/2-inch shank diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with Zplus PVD coating for extended tool life in aluminum and non-ferrous alloys\u003c\/li\u003e\n  \u003cli\u003e40-degree high-helix angle promotes aggressive chip evacuation and reduces built-up edge in aluminum\u003c\/li\u003e\n  \u003cli\u003eVariable index (unequal flute spacing) dampens vibration and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eReduced neck diameter of 0.475 inches with 1-1\/8-inch neck length enables deep-pocket reach up to 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003eBall nose profile with 0.25-inch nose radius supports 3D contouring and radius floor finishing\u003c\/li\u003e\n  \u003cli\u003eh6 tolerance on both mill diameter and shank diameter for consistent runout and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum alloys and non-ferrous materials (Primary Workpiece Material Code: N).

Before inserting the tool, clean the toolholder bore and shank with a lint-free cloth to remove any chips, oil buildup, or burrs that could affect runout. Confirm TIR does not exceed 0.0003 inches after clamping, as specified for this tool. Do not use this end mill on ferrous materials; the Zplus coating and geometry are optimized for non-ferrous cutting and performance or tool life will be compromised on steel or cast iron.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch\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: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.475 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1-1\/8 inches (1.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1-3\/4 inches (1.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ -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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal (Code: N)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.304 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: 81546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51750874153266,"sku":"81546","price":172.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebc44854b31c482d3b4c8b908175f8a6_b7f597f6-baf3-4e50-b964-a9152cfdb9a4.jpg?v=1788920295","url":"https:\/\/voomisupply.com\/products\/helical-solutions-81546-ball-end-mill-1-2-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
