Measuring 0.3125 inches in diameter with a 0.4375-inch length of cut, this single-end mill runs a 45-degree helix angle with three spiral flutes for efficient chip evacuation. The bright uncoated finish is suited for non-ferrous applications where coating buildup could affect tool performance. Machining professionals and CNC operators use this tool in production and jobshop environments where tight tolerances and clean edge geometry are required.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for cutting aluminum, copper, brass, and other non-ferrous materials, matching the N-grade workpiece material classification. The 5\/16-inch shank diameter fits standard tool holders used on vertical machining centers and manual mills. Its 2.5-inch overall length keeps the tool rigid in typical shallow-to-medium-depth milling passes, reducing deflection on detail cuts and slotting operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for edge sharpness and wear resistance in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes aggressive chip flow and reduces heat buildup in aluminum\u003c\/li\u003e\n\u003cli\u003eThree spiral flutes balance chip clearance with cutting edge support\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry directly into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish optimized for aluminum and non-ferrous metals where coatings are unnecessary\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series A345 replacement-style solid carbide square end mill for use with standard 5\/16-inch tool holders on CNC machining centers and manual milling machines cutting aluminum and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC technician. Ensure the spindle is fully stopped and machine is powered down before changing tooling. Use a calibrated tool holder and torque the retention mechanism per the machine manufacturer specification. Confirm runout with a dial indicator before beginning a production run to avoid premature tool wear or dimensional error.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A345\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17003145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563609358642,"sku":"17003145","price":70.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a279e75c11166bbb64b3ba5ce19b1dca_9b37c095-d872-4b19-b199-911258148b85.jpg?v=1786499742","url":"https:\/\/voomisupply.com\/products\/seco-17003145-square-end-mill-5-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
