Built to Series 582 standards, this double-end tool features a 0.0591-inch cutting diameter ground from M42 high-cobalt steel, offering superior heat and wear resistance compared to standard M2 HSS. The 2-flute, spiral flute geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Center-cutting capability allows for direct plunging into the workpiece without a pre-drilled pilot hole. The uncoated finish makes this end mill a solid choice for applications where re-sharpening is expected.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for light-duty slotting, profiling, and plunging operations on milling machines and CNC machining centers. The 0.1875-inch length of cut and 0.1875-inch shank diameter make it appropriate for close-tolerance work in tight spaces or small-feature geometry. The 2-1\/4-inch overall length provides adequate reach while maintaining rigidity. Machinists and tool-and-die professionals working with stainless steel, alloy steel, and other demanding materials will find the M42 cobalt construction effective for extended run cycles at elevated cutting temperatures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved hardness and heat resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eDouble-end design extends tool life by providing two usable cutting ends\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle spiral flutes promote chip evacuation and reduce cutting pressure\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard milling setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for re-sharpening and use with cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill compatible with 3\/16-inch collets, ER-style collet chucks, and end mill holders used on manual and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and the power is locked out before loading or changing the tool. Secure the shank fully within the collet or holder to the recommended engagement depth to prevent pullout under cutting loads. Verify runout with a dial indicator before commencing cuts on close-tolerance work.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0591 inches (1.50 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: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches (2-1\/4 inches)\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\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\u003eEnd Type\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\u003eSeries\u003c\/strong\u003e: 582\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: 5827200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748530880818,"sku":"5827200","price":67.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/131a4ab5e0f37a54dafcabc5ef31ebfa.jpg?v=1788894897","url":"https:\/\/voomisupply.com\/products\/osg-5827200-square-end-mill-0-0591-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
