It features a 5\/8-inch mill diameter, a 3\/4-inch length of cut, and a 37-degree helix angle that promotes aggressive chip evacuation and smooth cutting action. The ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in ferrous and non-ferrous applications. Micrograin carbide construction provides the rigidity needed for tight-tolerance work. This is a single-end, right-hand cutting tool with a stub-length profile, well suited to jobs where shorter projection reduces deflection.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, knee mills, and similar milling equipment where close tolerances and clean square shoulders are required. The stub-length design and 5\/8-inch shank diameter make it a practical choice for slotting, profiling, and peripheral milling in steel, aluminum, and similar materials. It is centercutting, allowing direct plunge entry without a pre-drilled pilot hole. Machinists and toolroom technicians handling production or job-shop work will find this a standard-duty replacement or new-setup tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-inch mill diameter with a tolerance of +0.000 \/ -0.002 inches for controlled fit and finish\u003c\/li\u003e\n\u003cli\u003e3 flutes with right-hand spiral flute direction for efficient chip removal\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle reduces cutting forces and improves surface finish\u003c\/li\u003e\n\u003cli\u003eZrN coating increases wear resistance and extends tool life across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction provides rigidity and resistance to chipping\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-setup tool for standard 5\/8-inch collet or end mill holders used in CNC machining centers and conventional milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the shank in a properly sized collet or end mill holder, ensuring the full recommended engagement length is gripped to minimize runout and deflection. Confirm spindle direction is set to right-hand rotation before operation. Follow machine manufacturer guidelines and applicable shop safety standards when setting tool offsets and feeds and speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\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\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inches (0.75 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.625 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 315180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755183571250,"sku":"315180","price":242.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd374202f15ba442bb3cd90720173839.jpg?v=1788951940","url":"https:\/\/voomisupply.com\/products\/accupro-315180-square-end-mill-5-8in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
