Built from M42 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard HSS tooling, making it well suited for harder workpiece materials and higher cutting speeds. The 0.375-inch diameter cutting geometry features 2 spiral flutes with a 30-degree helix angle and a right-hand cut, right-hand flute configuration. Center-cutting capability allows plunge entry as well as conventional peripheral milling.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical mills, knee mills, CNC machining centers, and manual machines where a 3\/8-inch shank is the specified toolholder size. With a 0.75-inch length of cut and a 1.75-inch reach length, it handles shallow-to-moderate depth passes in production and maintenance machining environments. It ships uncoated and falls within the OSG Series 527 regular-length product family. Typical users include machinists, tool and die makers, and maintenance professionals working across job shops and manufacturing facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat resistance over standard HSS tooling\u003c\/li\u003e\n  \u003cli\u003e30-degree spiral helix promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle use\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 1.75 inches accommodates stepped or recessed features\u003c\/li\u003e\n  \u003cli\u003eUncoated finish for use with a broad range of cutting fluids and workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for any machine tool accepting a 3\/8-inch straight shank end mill holder, collet chuck, or shrink-fit toolholder; part of the OSG Series 527 regular-length cobalt end mill line.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician using an appropriate collet, end mill holder, or set-screw-style toolholder rated for the 0.375-inch shank diameter. Ensure the toolholder is clean and free of chips before seating the shank to the recommended engagement depth. Confirm spindle direction is set to right-hand rotation before starting the cut. Follow the machine manufacturer and shop safety guidelines for RPM, feed rate, and depth of cut based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.700 - 0.800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.3125 inches (3-5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.75 inches (1-3\/4 inch)\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 (M42 HSS)\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\u003eExtended Reach\u003c\/strong\u003e: Yes\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: 527\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: 5270500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51788728697138,"sku":"5270500","price":69.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2fb741199ee46527808390c4121ff351.jpg?v=1789231861","url":"https:\/\/voomisupply.com\/products\/osg-5270500-square-end-mill-0-375-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
