Built to M42 cobalt material grade, this double-end tool features a 3\/4 inch cutting diameter, a 1-5\/16 inch length of cut, and a 5 inch overall length. The TiN (titanium nitride) coating reduces friction and extends tool life in ferrous and non-ferrous materials. With 2 spiral flutes and a 30-degree helix angle, it produces efficient chip evacuation during peripheral and slot milling. Machinists and tool-and-die professionals use this end mill in manual and CNC machining centers for general-purpose material removal.\u003c\/p\u003e\u003cp\u003eThis end mill suits production and maintenance machining environments where a center-cutting, right-hand cut tool is required. The right-hand flute configuration and 30-degree helix make it appropriate for steel, stainless steel, and other moderate-to-hard workpiece materials. Its 3\/4 inch shank diameter accommodates standard collet chucks and end mill holders commonly found in vertical machining centers and knee mills. The double-end design extends usable tool life by providing two cutting ends per shank.\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\u003eTiN finish reduces friction and improves tool life in demanding cuts\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip flow and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production end mill compatible with 3\/4 inch collet chucks, shrink-fit holders, and end mill holders used in vertical machining centers, knee mills, and similar equipment.

Secure the shank in a properly sized collet or end mill holder and verify runout before beginning a cut. Inspect both cutting ends for chipping or wear before each use. Follow the machine tool manufacturer and OSG published cutting data for recommended speeds and feeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/16 inch (1.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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: 5223105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748547625266,"sku":"5223105","price":214.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e31b95c4b28ddaf1a0fde51f30a197d_cf63ccd3-dc3c-4d66-b09d-3b4535d6070b.jpg?v=1788895106","url":"https:\/\/voomisupply.com\/products\/osg-5223105-square-end-mill-3-4-inch-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
