It features a 5\/8 inch cutting diameter with a 4 inch length of cut, giving it extended reach capability for deep-pocket and side-milling work. The two-flute spiral design with a 45-degree helix angle promotes aggressive chip evacuation while maintaining surface finish quality. A ZrN (zirconium nitride) coating reduces friction and extends tool life when cutting ferrous and non-ferrous materials. The micrograin carbide substrate adds toughness and wear resistance. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual milling machines used in production shops, toolrooms, and job shops. The centercutting geometry allows the tool to plunge directly into a workpiece, enabling slotting, profiling, and pocket milling without a pre-drilled entry hole. The right-hand cut and right-hand flute configuration fits standard spindle rotation on conventional vertical and horizontal milling setups. With an 8 inch overall length, it handles applications where standard-length tools cannot reach the full depth of the feature being machined.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and extends cutting tool life\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle improves chip flow in deep cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral configuration suits slotting and pocket milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle use\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 square end mill for standard 5\/8 inch collet or end mill holders on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Secure the shank in a compatible 5\/8 inch collet, end mill holder, or shrink-fit holder and verify runout before cutting. Confirm that spindle speed and feed rate are set per the material being machined before engaging the workpiece. Inspect the tool for chipping or wear at regular intervals, as carbide tools can fracture if feed rates exceed the tool geometry limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 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: 0.8 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: 313414\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737986040114,"sku":"313414","price":411.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db101af4c33bd0573d6c3177417cab72.jpg?v=1788795462","url":"https:\/\/voomisupply.com\/products\/accupro-313414-square-end-mill-5-8-in-2-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
