The cutter measures 0.4724 inches (12.00 mm) in diameter with a 13\/16-inch length of cut, a 1\/2-inch shank diameter, and a 3-3\/4-inch overall length. Manufactured from M42 cobalt high-speed steel, it delivers better red hardness than standard M2 tooling, making it a solid choice when cutting tougher steels or working in conditions where coolant is limited. The 30-degree helix and spiral flute geometry promote chip evacuation and smooth cutting action across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for vertical machining centers, knee mills, and manual milling machines in job shop, maintenance, and production environments. The double-end configuration provides two usable cutting ends, extending tool life and reducing cost per edge. The centercutting design allows plunge milling in addition to peripheral and slot milling. Right-hand cut and right-hand flute orientation match standard spindle rotation on conventional milling setups. It is installed and changed by machinists and tool-and-die technicians working in metalworking applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard M2 tooling\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, lowering cost per edge\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish compatible with re-sharpening and suitable for a wide range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle direction compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the OSG Series 582 regular-length cobalt double-end square end mill line.

Ensure the machine spindle is fully stopped and the drawbar or collet nut is secured before inserting or removing the tool. Use a properly sized collet or end mill holder matched to the 1\/2-inch shank diameter to maintain concentricity and minimize runout. Follow shop safety procedures and applicable machine guarding requirements when operating milling equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4724 inches (12.00 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: 0.8125 inches (13\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.750 inches (3-3\/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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\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\u003eEnd Style\u003c\/strong\u003e: Double End\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: 5821100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727557427506,"sku":"5821100","price":103.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a7e5ba52d5ae8f9cb2a75c18734ba25.jpg?v=1788679311","url":"https:\/\/voomisupply.com\/products\/osg-5821100-square-end-mill-0-4724-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
