Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to interrupted cuts, harder steels, and abrasive materials where standard HSS tooling falls short. The cutter measures 29\/64 inch (0.4531 inch) in diameter with a 13\/16 inch (0.8125 inch) length of cut, a 1\/2 inch shank diameter, and a 3-3\/4 inch overall length. The 30-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish makes the tool suitable for use with cutting fluid in conventional milling setups.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard milling applications in job shop, tool room, and production environments. The double-end design provides two usable cutting ends per tool, extending service life and reducing tooling cost per operation. The 2-flute configuration is well suited to slotting and plunge cuts where chip clearance is a priority. It falls within the OSG Series 522 regular-length category, targeting general-purpose material removal in manual and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for improved heat resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eDouble-end design yields two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e2-flute geometry supports slotting and plunge milling operations\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with flood coolant and cutting oils\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement end mill for 1\/2 inch collet or end mill holders on manual knee mills and CNC machining centers requiring a 29\/64 inch diameter, 2-flute square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and tooling technicians using a standard end mill holder or collet chuck sized for a 1\/2 inch shank. Ensure the machine spindle is fully stopped and locked before changing tooling. Verify runout with a dial indicator after seating the tool to minimize chatter and premature wear. Follow shop-specific feeds and speeds for cobalt tooling and the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 29\/64 inch (0.4531 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13\/16 inch (0.8125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches (3.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/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: 522\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: 5227000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731912753458,"sku":"5227000","price":112.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e68044e39cc89c270ee7d966699d84f_a42b81ce-66c5-49c7-bd2a-86125c0ccc77.jpg?v=1788736496","url":"https:\/\/voomisupply.com\/products\/osg-5227000-square-end-mill-29-64-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
