Built on the End Mills for Aluminum series, this 3-flute tool features a 40-degree helix angle, variable pitch (variable index) geometry, and a reduced neck profile that improves clearance and rigidity in deep-pocket and contour work. The Zplus coating provides lubricity and edge protection suited to non-ferrous cutting. At 3\/16 inches in diameter with a 7\/32-inch length of cut, this tool is sized for fine detail work, slotting, and profiling passes where a smaller cutter footprint is required. Machinists, CNC programmers, and tool-and-die professionals working in production or prototype aluminum environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for use in aluminum and other non-ferrous materials where chip evacuation and surface finish are priorities. The reduced neck extends usable reach to 1.312 inches, allowing access to deeper features without requiring a longer overall tool. The variable index flute spacing reduces harmonic chatter during high-speed machining. The straight-cylindrical shank seats directly into standard ER or side-lock toolholders. It is a single-end, right-hand cutting, right-hand flute configuration running in conventional CNC milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-flute, 40-degree helix geometry optimized for aluminum chip evacuation\u003c\/li\u003e\n\u003cli\u003eVariable index (non-uniform flute spacing) reduces chatter at high RPM\u003c\/li\u003e\n\u003cli\u003eReduced neck design extends reach to 1.312 inches for deep-feature access\u003c\/li\u003e\n\u003cli\u003eZplus coating improves lubricity and edge life in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports plunge entry moves\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction throughout for rigidity and dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification solid carbide end mill for aluminum and non-ferrous milling operations where a 3\/16-inch diameter, reduced-neck, variable-pitch 3-flute geometry is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Secure the straight-cylindrical shank in a clean, properly sized collet or toolholder, torquing to the toolholder manufacturer specification. Verify runout before cutting. Confirm spindle speed, feed rate, and depth-of-cut parameters are appropriate for aluminum before initiating the program — do not transfer speeds and feeds from steel toolpaths without adjustment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 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: 7\/32 inches (0.2187 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.312 inches (1-5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\/Finish\u003c\/strong\u003e: Zplus\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: End Mills for Aluminum - 3 Flute - Square - 40 deg Helix - Variable Pitch - Reduced Neck\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 82472\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51732523876658,"sku":"82472","price":88.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e58b1abe7386f46ee075bf69be3ec513_384d4edf-8c7c-4129-9e0e-a5c2d0c277f3.jpg?v=1788743992","url":"https:\/\/voomisupply.com\/products\/helical-solutions-82472-square-end-mill-3-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
