Built from M42 cobalt high-speed steel, this single-end tool offers improved heat and wear resistance compared to standard HSS, making it well suited for harder ferrous materials and interrupted cuts. It carries a 5\/8 inch cutting diameter, a 2-1\/2 inch length of cut, and a 4-5\/8 inch overall length. The bright, uncoated finish means the tool is ready to run as supplied, with no coating concerns for regrinding. Four right-hand spiral flutes at a 30-degree helix angle provide efficient chip evacuation and smooth cutting action across a range of feed and speed conditions.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for general-purpose milling tasks in job shop, maintenance, and production environments. The long-series geometry, with its 2-1\/2 inch length of cut, accommodates deeper pockets, slots, and peripheral milling passes where a standard-length tool cannot reach. It is centercutting, allowing direct plunge entry without a pre-drilled start hole. Suitable for ferrous metals including alloy steel, tool steel, and stainless, as well as some non-ferrous applications. Machinists, tool-and-die makers, and skilled trades professionals in manufacturing environments are the typical end users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for enhanced heat resistance and extended tool life in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut (2-1\/2 inches) reaches deeper pockets and slots\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — compatible with regrinding services and standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 5\/8 inch shank square end mill applications requiring a long-series cobalt tool.

Secure the shank firmly in a collet, end mill holder, or Weldon-style holder, torquing set screws per the toolholder manufacturer's specifications. Ensure the spindle and machine are fully de-energized and locked out before changing tooling. Verify runout with a dial indicator after seating the tool to confirm proper holder engagement before beginning a cut.\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: 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\u003eLength of Cut\u003c\/strong\u003e: 2-1\/2 inches (2.5000 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\u003eOverall Length\u003c\/strong\u003e: 4-5\/8 inches (4.6250 inches)\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCCC-C-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 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: 723-3309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710265033010,"sku":"723-3309","price":93.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73242efcc222384a4b4d618cfc73cad3.jpg?v=1788464955","url":"https:\/\/voomisupply.com\/products\/value-collection-723-3309-square-end-mill-5-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
