Built from M42 cobalt high-speed steel and finished with a TiN (titanium nitride) coating, it delivers extended tool life in demanding cutting applications. The 13\/16 inch (0.8125 inch) cutting diameter pairs with a 1-7\/8 inch length of cut and a 3\/4 inch shank, making it well-suited for roughing passes on steel, stainless, and other ferrous materials. With 4 flutes and right-hand cutting and flute direction, it is a standard configuration recognized by machinists across job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical machining centers, knee mills, and manual milling machines where high-stock-removal roughing cuts are required. The cobalt M42 substrate handles elevated cutting temperatures better than standard M2 high-speed steel, which is useful when cutting harder alloys or when coolant is limited. The non-centercutting design means it is intended for peripheral and side milling passes, not plunge entry. It is installed by machinists, toolroom operators, and CNC setup technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e13\/16 inch (0.8125 inch) mill diameter with 3\/4 inch shank for secure tool holding\u003c\/li\u003e\n\u003cli\u003e1-7\/8 inch length of cut suited for moderate-depth roughing passes\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand cut and right-hand helix geometry\u003c\/li\u003e\n\u003cli\u003eSingle-end design with non-centercutting tip — peripheral and side milling use only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank roughing end mill compatible with 3\/4 inch collets, end mill holders, and milling chucks used in conventional and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank fully into the holder to the recommended minimum engagement depth per the tool holder manufacturer. Because this is a non-centercutting end mill, do not use it for direct plunge cuts — ramp or helical entry strategies are required when full-depth slot entry is needed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: TiN\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 (Fractional)\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 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: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 723-6777\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714891776306,"sku":"723-6777","price":222.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25b5ac0e695669a8af0a9c29c3851e2e.jpg?v=1788507524","url":"https:\/\/voomisupply.com\/products\/value-collection-723-6777-roughing-end-mill-13-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
