It features a 1\/4 inch cutting diameter, a 3\/4 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the tool-workpiece interface and extends tool life in slot milling, profiling, and finishing passes. The 4-flute geometry and 40-degree helix angle promote efficient chip evacuation and a smooth surface finish. A TiAlN coating provides thermal resistance and hardness at elevated cutting temperatures. Overall length is 2-1\/2 inches with a 1\/4 inch shank diameter. Intended for use by machinists and tool-and-die professionals on CNC mills and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose milling applications in job shops, tool rooms, and production environments. The corner radius geometry is particularly well suited to finishing operations where sharp inside corners would cause stress risers or where a controlled radius is called out on the part drawing. Right-hand cut, right-hand flute direction, and centercutting capability allow plunge entry as well as conventional and climb milling. The regular-length body keeps deflection low during side milling at moderate depths. Typical materials include alloy steels, stainless steels, and hardened materials where TiAlN coating performance is beneficial.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03 inch corner radius reduces tool stress and improves edge strength at cut transitions\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides high-temperature hardness and oxidation resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute, 40-degree right-hand helix for efficient chip evacuation and smooth finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch, right-hand cut geometry suitable for a wide range of machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of OSG Series 2015.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the end mill. Set tool length offset in the CNC control before cutting. Follow the machine tool manufacturer and cutting tool supplier feed-and-speed recommendations for the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3 inches length x 0.5 inches width x 0.5 inches height\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: 20150211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734863774002,"sku":"20150211","price":173.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c247ede1403f597becca8539b9d0aea7.jpg?v=1788767425","url":"https:\/\/voomisupply.com\/products\/osg-20150211-corner-radius-end-mill-1-4-in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
