Built from M42 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard HSS tooling. The cutter measures 0.6299 inches (16 mm) in diameter with a 1-5\/8 inch length of cut and a 5\/8 inch shank diameter, making it a right-hand spiral flute tool suited for slotting, profiling, and peripheral milling. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces across a range of workpiece materials. The bright uncoated finish is standard for cobalt tooling used in applications where coating is not required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical machining centers, knee mills, and manual milling machines where a regular-length, single-end cobalt tool is called for. It is centercutting, allowing direct plunge entry into the workpiece without a pre-drilled hole. The 4-flute configuration provides a good balance between material removal and chip clearance, making it practical for steels, stainless, cast iron, and similar ferrous materials at moderate cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for increased heat resistance versus standard HSS end mills\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating degradation concerns when regrinding\u003c\/li\u003e\n  \u003cli\u003eSingle-end tool with 5\/8 inch straight shank for standard collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end square end mill for use in any milling machine or machining center equipped with a 5\/8 inch collet, end mill holder, or Weldon-style side-lock holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers following standard machine tool setup procedures. Ensure the spindle is fully stopped and locked out before loading or removing the tool. Seat the shank fully in the collet or holder and torque the retention hardware to the machine or toolholder manufacturer specifications. Verify runout with a dial indicator after mounting and before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\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: 1.625 inches (1-5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches (3-3\/4 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCCC-C-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-8686\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712241107250,"sku":"723-8686","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/787130bac4f8015a7d2f8ebf4e00f80d.jpg?v=1788485566","url":"https:\/\/voomisupply.com\/products\/value-collection-723-8686-square-end-mill-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
