Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention in demanding cutting conditions. The 7\/16-inch cutting diameter pairs with a 1-3\/4-inch length of cut, a 1\/2-inch shank diameter, and a 3-3\/4-inch overall length. The 45-degree helix spiral flute geometry promotes efficient chip evacuation and smooth cutting action. This end mill is centercutting, allowing plunge entry, and runs right-hand cut with right-hand flute direction. It is supplied uncoated and belongs to OSG Series 535.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose slot milling, profiling, and peripheral milling in machine shop and production environments. It is a long-length style, placing it in the 1.5-inch to 2.0-inch length-of-cut range class, which provides extended reach for deeper pockets and stepped features. Machinists and CNC operators working with steel, stainless steel, cast iron, and similar materials will find this tool appropriate for their setups. It is a single-end tool intended for use in conventional vertical and horizontal milling machines and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle spiral flute for improved chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge cutting without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute, standard orientation for most milling setups\u003c\/li\u003e\n  \u003cli\u003eLong-length series providing extended reach into deep slots and pockets\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with standard cutting fluids and coolants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or production-use end mill for applications requiring a 7\/16-inch diameter, 1\/2-inch shank, long-length cobalt square end mill in OSG Series 535 tooling programs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator using an appropriate collet, end mill holder, or set-screw holder sized for the 1\/2-inch shank. Verify runout and tool projection before engaging the cut. Follow machine tool manufacturer guidelines for spindle speed and feed rate based on workpiece material and depth of cut. Never exceed the tool's rated length of cut in a single pass without confirming rigidity and deflection limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inches (1.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 535\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Square Single End\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: 5351000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739040678194,"sku":"5351000","price":92.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f385ef12e0dedab1d9b2343ee00a8e1a.jpg?v=1788808379","url":"https:\/\/voomisupply.com\/products\/osg-5351000-square-end-mill-7-16-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
