It features a 5\/16-inch diameter with a 0.0300-inch corner radius and a 4-flute, right-hand spiral configuration. The cutting edge is 13\/16 inches long, and the tool runs 2-1\/2 inches overall. An AlTiN coating improves heat resistance and wear life at elevated cutting temperatures. The micrograin carbide substrate adds toughness and edge retention. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece as well as cut along the periphery. Machinists and CNC operators in job shops, tool rooms, and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling hardened steels, stainless steels, cast iron, and other ferrous materials where heat generation is a concern. The AlTiN coating performs well in dry or minimum-quantity lubrication (MQL) cutting conditions. The corner radius geometry reduces stress concentrations at the cutting edge, extending tool life compared to a sharp-corner end mill in interrupted or heavy-feed applications. It is appropriate for profiling, slotting, and finishing passes where a controlled corner break is required on the finished part.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high-temperature wear resistance in ferrous and hard-material cutting\u003c\/li\u003e\n  \u003cli\u003e0.0300-inch corner radius reduces edge chipping and improves surface finish at corners\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral with variable helix for reduced chatter and vibration\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eMatching 5\/16-inch shank and cutter diameter for standard collet or end mill holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 5\/16-inch collets, end mill holders, or shrink-fit tooling systems on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. The tool should be secured in a clean, properly sized collet or end mill holder and torqued to the toolholder manufacturer's specification. Inspect the shank and cutting edges for chips or contamination before mounting. Confirm spindle direction is set to right-hand rotation before engaging the cut.\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 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13\/16 inches (0.8125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 95168583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728433152306,"sku":"95168583","price":270.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0c5d09469f32fa90a5745e7918a72dc.jpg?v=1788691083","url":"https:\/\/voomisupply.com\/products\/accupro-95168583-corner-radius-end-mill-5-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
