It features a 5\/16 inch (0.3125 inch) mill diameter with a matching 5\/16 inch straight cylindrical shank. The 35-degree right-hand helical flute geometry promotes efficient chip evacuation and reduces built-up edge when cutting aluminum alloys. A Zplus coating adds lubricity and surface hardness to extend tool life in non-ferrous applications. The reduced neck design provides extended reach of 1.125 inches, making this end mill well suited for profiling slots and pockets where clearance is a factor. Licensed machinists and CNC operators install this tool in vertical machining centers and milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for aluminum and other non-ferrous materials. The reduced neck, extended reach geometry allows access to deeper features without sacrificing rigidity at the cutting zone. With a length of cut of 0.4375 inch (7\/16 inch) and an overall length of 4 inches, it fits standard CNC tool holders and manual mills configured for 5\/16 inch shank tooling. It is centercutting, allowing plunge entry directly into the workpiece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16 inch diameter solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e3-flute, 35-degree right-hand helical geometry optimized for aluminum chip evacuation\u003c\/li\u003e\n\u003cli\u003eZplus coating improves lubricity and extends tool life in non-ferrous cuts\u003c\/li\u003e\n\u003cli\u003eReduced neck design with 1.125 inch reach length for deeper feature access\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard 5\/16 inch collets and tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new installation for CNC machining centers and manual mills accepting 5\/16 inch straight shank tooling; confirmed for use in aluminum and non-ferrous milling applications per the HELICAL SOLUTIONS End Mills for Aluminum 3 Flute Square 35 degree Helix Reduced Neck series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into a clean, properly torqued collet or end mill holder to the depth recommended by the tool holder manufacturer. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates wear on carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.4375 inches (7\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.125 inches (1-1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.148 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: 04167\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51748238033202,"sku":"04167","price":78.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2b8b3d0b97733bef3a8b25536af6904_de8d7d30-7879-4355-9119-9954079646d0.jpg?v=1788890898","url":"https:\/\/voomisupply.com\/products\/helical-solutions-04167-square-end-mill-5-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
