It features a 3\/8 inch diameter cutting face with a 0.0900 inch corner radius, a 4-flute spiral geometry, and an AlTiN+ coating that provides heat resistance and extended tool life at elevated cutting speeds. The overall length is 2.5 inches with a 7\/8 inch length of cut. This is a single-end, centercutting tool, meaning it can plunge directly into material as well as perform peripheral and slot milling. Machinists and tool-and-die professionals typically install and run this end mill on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on hardened steels, stainless, and high-temp alloys where a corner radius is required to reduce stress concentrations and improve surface finish at part edges. The right-hand cutting direction and spiral flute design support efficient chip evacuation in both roughing and finishing passes. It is a single-end tool, so the shank end is not a cutting surface. Typical applications include die cavities, mold details, stepped pockets, and contoured profiles where a sharp corner is not acceptable by design or specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0900 inch corner radius reduces edge stress concentration and improves surface finish on milled profiles\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating provides high hardness and oxidation resistance for extended tool life in ferrous and high-temp alloys\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry supports efficient chip evacuation and higher feed rates versus 2-flute designs\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability in close-tolerance applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual mill spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill suitable for use in standard milling tool holders accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool should be installed by a qualified machinist using an appropriate end mill holder, collet chuck, or hydraulic holder rated for the shank diameter. Ensure the spindle is fully stopped and machine is in a safe state before inserting or removing the tool. Verify runout with a dial indicator after tool installation to maintain dimensional accuracy. Follow the machine tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0900 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: 0.8750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14788488\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737207079218,"sku":"14788488","price":98.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d9eca1d194c6761e73f6d0bc2a8299a.jpg?v=1788785597","url":"https:\/\/voomisupply.com\/products\/accupro-14788488-corner-radius-end-mill-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
