It features a 5\/16 inch cutting diameter, a 13\/16 inch length of cut, and a 2-1\/2 inch overall length. The three-flute, spiral-flute geometry runs at a 45-degree helix angle, which promotes efficient chip evacuation in soft and gummy materials. The bright, uncoated finish suits applications where coating interaction with aluminum is undesirable. Micrograin carbide construction provides rigidity and edge retention in high-speed passes. This end mill is a single-end, center-cutting tool with a straight shank, installed by machinists and CNC operators in precision machining environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for light-to-moderate material removal in aluminum alloys and other non-ferrous workpiece materials. The center-cutting capability allows direct plunge entry without a pre-drilled pilot hole, supporting slotting, profiling, and pocket milling operations. The right-hand cut and right-hand flute configuration is standard for conventional CNC vertical and horizontal machining centers. The 5\/16 inch shank diameter matches the cutting diameter, keeping the tool profile consistent for close-tolerance toolpath work in smaller-part fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge stability and rigidity\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral geometry with 45-degree helix for efficient chip removal in aluminum\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design supports direct plunge entry and slot milling\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish optimized for aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute — standard CNC orientation\u003c\/li\u003e\n  \u003cli\u003eStraight shank with tight diameter tolerance for secure collet or end-mill-holder grip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills with standard 5\/16 inch collets or end mill holders.

Ensure the machine spindle is fully stopped and the tool is secured before tightening the holder. Apply appropriate cutting speeds and feeds for the workpiece material per the machine tool documentation. Inspect the cutting edges for chips or wear before each use, as carbide tools are brittle and can fracture if seated improperly or run at incorrect parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13\/16 inch (0.8125 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\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 \/ -0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 17003146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558383911218,"sku":"17003146","price":77.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a279e75c11166bbb64b3ba5ce19b1dca.jpg?v=1786410714","url":"https:\/\/voomisupply.com\/products\/seco-17003146-square-end-mill-5-16-inch-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
