It features a 1\/2 inch diameter, a 5\/8 inch length of cut, and a 6 inch overall length, making it well suited for extended reach applications. The AlCrTiN coating provides excellent heat and wear resistance, supporting higher cutting speeds and longer tool life in hard or abrasive materials. With a 5-flute, right-hand spiral configuration and a variable index design, this end mill delivers improved chip evacuation and reduced chatter. The 0.020 inch corner radius protects the cutting edge and produces a consistent radius at the base of milled features. Licensed machinists and CNC operators install and operate this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for single-end, centercutting use in vertical and horizontal CNC machining centers. The extended reach design, with a 4-1\/8 inch reach length and a 0.475 inch neck diameter, allows access to deep pockets, cavities, and stepped features that standard-length tools cannot reach. It is appropriate for use in mold and die work, aerospace components, and precision part production where tight tolerances and consistent corner geometry are required. The micrograin carbide substrate supports rigidity and edge retention across a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrTiN coating for elevated heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e5-flute, right-hand spiral geometry with variable index for reduced chatter and improved surface finish\u003c\/li\u003e\n  \u003cli\u003e0.020 inch corner radius for edge protection and consistent radial blending at pocket floors\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 4-1\/8 inch reach length and reduced 0.475 inch neck diameter for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without pre-drilled pilot holes\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and dimensional stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers accepting a 1\/2 inch straight shank toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified machinist or CNC operator. Secure the 1\/2 inch shank in a compatible collet or end mill holder and verify runout before beginning a cutting operation. Ensure the machine spindle is fully stopped and the tool is locked out before changing or inspecting the end mill. Do not exceed the tool manufacturer's recommended cutting parameters for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.475 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 4-1\/8 inches (4.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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: AlCrTiN\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 Index\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\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: 312233\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747440165170,"sku":"312233","price":198.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/218a9bb0ec85e0bcef2be0718319066c_15bcd493-0a82-4b76-9b5f-409c9eae9c4c.jpg?v=1788880261","url":"https:\/\/voomisupply.com\/products\/accupro-312233-corner-radius-end-mill-1-2-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
