It features a 5\/8-inch cutting diameter, a 3-inch length of cut, and a 6-inch overall length, making it well suited for deep-reach slotting, profiling, and peripheral milling. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. An nACRo finish coating improves wear resistance and thermal stability during high-speed cutting. With a micrograin carbide substrate and spiral flute geometry, this tool delivers consistent performance in ferrous and non-ferrous applications. Licensed machinists and CNC operators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual milling machines for general-purpose material removal. The centercutting design allows direct plunge entry into workpieces without a pre-drilled hole. The right-hand cut and right-hand flute configuration is standard for conventional and climb milling. The 5\/8-inch shank diameter fits standard ER collets, end mill holders, and milling chucks. Typical applications include slot milling, contour profiling, and step milling in steel, stainless steel, cast iron, and aluminum alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003enACRo finish coating for improved heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle for aggressive chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute for standard milling operations\u003c\/li\u003e\n  \u003cli\u003e2-flute configuration provides clearance for chip removal in slotting applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-inch shank square end mill compatible with ER collet chucks, Weldon-style end mill holders, and hydraulic milling chucks on CNC and manual milling machines accepting 5\/8-inch shanks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before securing the end mill. Tighten the collet or set screw to the tool holder specification using calibrated tooling. Verify runout with a dial indicator before beginning a cut to avoid premature tool wear or workpiece damage.\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: 3 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: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: nACRo\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12178836\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738717880626,"sku":"12178836","price":419.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d6f02e45853620479f8cd4013a537a4.jpg?v=1788803333","url":"https:\/\/voomisupply.com\/products\/accupro-12178836-square-end-mill-5-8-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
