Built from M42 cobalt high-speed steel, this double-end tool features a 3\/16 inch cutting diameter, a 1\/2 inch length of cut, and a 2-1\/4 inch overall length. The 30-degree spiral flute geometry promotes efficient chip evacuation and reduces heat buildup during cuts. With two flutes and a centercutting design, this end mill handles plunge cutting, slotting, and peripheral milling. It is suited for machinists and tool-and-die professionals working on ferrous and non-ferrous materials in manual or CNC machine setups.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard milling operations in job shop, maintenance, and production environments. The 3\/16 inch shank diameter matches common collet and chuck setups on knee mills, bed mills, and CNC machining centers. The regular-length configuration keeps it stable in tight-tolerance work. The double-end design extends tool life by providing two usable cutting ends before the tool is retired, making it a practical choice for high-frequency applications where tool economy matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a wide range of general milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for standard 3\/16 inch collet and end mill holder setups on manual and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard tooling procedures. Ensure the machine spindle is fully powered down and at rest before inserting or removing any end mill. Seat the shank fully into the collet or tool holder and torque the retention mechanism according to the machine or toolholder manufacturer guidelines. Verify runout with a dial indicator before beginning any cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 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\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\u003eSeries\u003c\/strong\u003e: 563\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5638000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738615152946,"sku":"5638000","price":59.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73d70672d005eb2a1aabc6c7b1ad8aa8.jpg?v=1788801801","url":"https:\/\/voomisupply.com\/products\/osg-5638000-square-end-mill-3-16-in-2-flute-cobalt-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
