Built from M42 cobalt high-speed steel, this tool handles tough ferrous and non-ferrous materials with a 7\/8 inch (0.875 inch) cutting diameter and a 5-flute geometry that distributes chip load evenly across the cutting edge. The bright, uncoated finish suits general-purpose roughing passes where coating adhesion is not a requirement. A 3\/4 inch shank diameter provides solid tool holding in standard collets and end mill holders. This tool is installed and operated by machinists and tool-room professionals in manual and CNC machining environments.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is suited for roughing operations in vertical mills, knee mills, and CNC machining centers. The 5-flute configuration increases feed rate capability compared to standard 4-flute designs, making it effective for hogging stock on steel, stainless, cast iron, and similar materials. The right-hand cut and right-hand flute direction are standard for conventional and climb milling on most machine setups. It is not center-cutting, so it is not intended for plunge entry without a pre-drilled hole or ramping strategy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8 inch (0.875 inch) cutting diameter with 1.875 inch length of cut for deep roughing passes\u003c\/li\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e5-flute design increases material removal rate and surface contact per revolution\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch shank diameter fits standard end mill holders and collet chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation on most mill types\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating interaction concerns with cutting fluids or certain materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct drop-in for single-end roughing end mill applications requiring a 7\/8 inch diameter, 3\/4 inch shank, 5-flute cobalt tool in standard end mill holders and collet systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully in the tool holder to the manufacturer-recommended engagement depth before tightening. Because this end mill is not center-cutting, avoid direct plunge cuts — use a ramping or helical entry path or pre-drill the entry point. Inspect the cutting edges and shank for damage before each use, and ensure spindle speed and feed rate are set per the material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inch (0.875 inch)\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: 1-7\/8 inches (1.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\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\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 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: 723-5781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691499389234,"sku":"723-5781","price":138.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d2e9dcf13bbee6b43384ea37655a47c.jpg?v=1788286000","url":"https:\/\/voomisupply.com\/products\/value-collection-723-5781-roughing-end-mill-7-8-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
