It features a 5\/16-inch diameter with a 1\/8-inch corner radius, a 1-1\/8-inch length of cut, and a 4-flute right-hand spiral configuration. The micrograin carbide construction provides edge retention and dimensional stability under demanding cutting conditions. At 3 inches overall length with a 5\/16-inch shank, this single-end, centercutting tool handles both plunge and peripheral cuts. The bright uncoated finish suits general-purpose ferrous and non-ferrous machining where coating is not required.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills in job shop, tool-and-die, and production environments. The long flute length and corner radius geometry make it well matched to profile milling, pocketing, and finishing operations where a radiused corner is required on a workpiece edge or floor transition. The right-hand cutting direction and spiral flute type are standard for conventional and climb milling setups on vertical and horizontal spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003e1\/8-inch corner radius reduces stress concentrations at milled corners\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip evacuation with surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and cutting direction for standard spindle setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 5\/16-inch collet or end mill holder setups on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a collet chuck, end mill holder, or shrink-fit toolholder sized for a 5\/16-inch shank. Always bring the spindle to a full stop and isolate machine power before changing tooling. Confirm runout with a dial indicator after seating the tool, and verify corner radius and diameter tolerances against part print requirements before beginning a production run.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.0000 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 12183023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747810935090,"sku":"12183023","price":65.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/386e53d4a4b30f43f62fd978c4137db1.jpg?v=1788885765","url":"https:\/\/voomisupply.com\/products\/accupro-12183023-corner-radius-end-mill-5-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
