It measures 0.0469 inches in diameter with a 0.005-inch corner radius and delivers a 0.625-inch length of cut. The four-flute, right-hand spiral geometry provides efficient chip evacuation and smooth surface finishes on ferrous and non-ferrous materials. An AlTiN coating improves heat resistance and extends tool life in high-speed cutting applications. This single-end, centercutting tool is suited for machinists and CNC operators working in job shops, aerospace, and precision manufacturing.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical and horizontal milling operations where a corner radius profile is required to reduce stress concentrations and improve part durability. The 0.0469-inch diameter makes it well suited for fine detail work, tight pockets, and small-feature milling in hardened steels and high-temp alloys. The 1\/8-inch shank diameter fits standard collet toolholders on CNC machining centers and manual mills. It is a single-end tool, so once the cutting end is worn, the tool is replaced rather than flipped.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0469-inch mill diameter with 0.005-inch corner radius for controlled edge geometry\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral design for efficient chip removal and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge milling capability\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e1.5-inch overall length with 1\/8-inch shank for compatibility with standard collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills using 1\/8-inch collet toolholders requiring a corner radius end mill profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or collet is properly released before inserting or removing the tool. Verify collet runout and toolholder cleanliness before seating the shank to maintain dimensional accuracy. Follow machine manufacturer guidelines and applicable shop safety procedures when setting tool length offsets and cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0469 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 \/ -0.0008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.001 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: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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: 0.01 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12176889\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748859347250,"sku":"12176889","price":34.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7ed93f278034a81166c5369dfc7177a.jpg?v=1788899712","url":"https:\/\/voomisupply.com\/products\/accupro-12176889-corner-radius-end-mill-0-0469-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
