Built from M42 cobalt high-speed steel, it delivers excellent heat and wear resistance when cutting ferrous and harder alloy materials. The 5\/8-inch diameter tool features 4 flutes with a coarse pitch configuration, which reduces cutting forces, clears chips efficiently, and minimizes chatter during heavy roughing passes. The bright, uncoated finish maintains a sharp cutting edge and suits applications where coating-related dimensional buildup is a concern. Machinists and tool-and-die professionals use this end mill in manual and CNC milling machines for stock removal prior to finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing operations on ferrous metals and harder workpiece materials in both job-shop and production milling environments. The coarse pitch flute geometry breaks chips into manageable segments, reducing heat buildup and extending tool life in demanding cuts. With a 2.5-inch length of cut and 4.625-inch overall length, it provides adequate reach for most standard milling setups without sacrificing rigidity. Right-hand cutting and right-hand flute direction match conventional milling machine spindle rotation. This 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\u003eM42 cobalt HSS construction for improved heat resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch, 4-flute design promotes aggressive chip evacuation during roughing\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish preserves tight edge geometry with no coating buildup\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch shank diameter matches the 5\/8-inch mill diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration — no center-cutting capability, intended for peripheral roughing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for standard milling machines accepting a 5\/8-inch shank, including manual knee mills and CNC vertical machining centers with compatible collet or end mill holder tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Secure the 5\/8-inch shank in a properly sized end mill holder or collet chuck and torque the retention mechanism per the toolholder manufacturer specifications. Confirm spindle direction is set to right-hand rotation before engaging the cut. This tool is not center-cutting — do not plunge directly into solid material; use a pre-drilled hole or ramp entry for plunge-style operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.625 inches (4-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-5527\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691789156658,"sku":"723-5527","price":219.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fc2d31f24654177450a726af62b52a6.jpg?v=1788289712","url":"https:\/\/voomisupply.com\/products\/value-collection-723-5527-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
