Built from M42 cobalt high-speed steel, this double-end tool delivers durability and heat resistance in demanding cutting environments. It features a 0.2362-inch cutting diameter, a 0.5-inch length of cut, and a 30-degree helix angle with spiral flutes for efficient chip evacuation. The right-hand cut and right-hand flute geometry are standard for conventional CNC and manual milling setups. Machinists and tool-and-die professionals reach for this end mill when working on close-tolerance slots, pockets, and profile cuts where tool life and dimensional accuracy matter.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits residential shop and industrial production environments alike. It is suited for milling steel, stainless steel, cast iron, and other tough alloys where cobalt tooling outperforms standard high-speed steel. The 3\/8-inch shank diameter fits standard collets and end mill holders on vertical machining centers, knee mills, and CNC routers. The double-end design extends tool life by providing two usable cutting ends per tool, reducing overall tooling cost per operation. The 3-1\/8-inch overall length keeps overhang manageable for rigid setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for heat resistance and longer tool life in tough alloys\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flutes promote efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard milling machine spindles\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with cutting fluids on ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch collets and end mill holders on CNC machining centers, vertical knee mills, and manual milling machines.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware according to the machine tool manufacturer specifications. Always verify tool runout with a dial indicator before beginning a production cut, and use appropriate cutting fluid for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches (3-1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: 582\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5820400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730844156210,"sku":"5820400","price":72.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c5442749d41c6e173737b3d113e36c3.jpg?v=1788723748","url":"https:\/\/voomisupply.com\/products\/osg-5820400-square-end-mill-0-2362-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
