Built from M42 cobalt high-speed steel, it delivers improved heat and wear resistance over standard HSS tooling. The 0.5 inch cutting diameter and 0.5 inch length of cut are paired with a TiCN (Titanium Carbonitride) coating that reduces friction and extends tool life in demanding applications. With four spiral flutes at a 30-degree helix angle and a center-cutting design, this end mill handles both plunge and peripheral milling. Machinists and tool-and-die professionals use it for slotting, profiling, and finishing cuts on steel, alloy steel, and similar workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling machines, CNC machining centers, and manual knee mills equipped with a 0.5 inch collet or end mill holder. The 0.5 inch shank diameter and 2.5 inch overall length make it suited for general-purpose milling with moderate reach requirements. Its right-hand cut and right-hand flute orientation match the majority of conventional and CNC milling setups. The Series 541 designation identifies it within OSGs cobalt end mill family, and the single-end configuration is standard for this class of tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for increased red hardness and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves tool life in abrasive and hard materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard milling machine compatibility\u003c\/li\u003e\n  \u003cli\u003eNo chipbreaker, extended reach, variable helix, or variable index — straightforward general-purpose geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any milling setup accepting a 0.5 inch shank, including standard ER collet chucks, side-lock holders, and shrink-fit holders on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is de-energized before inserting or removing the end mill from the holder. Verify collet or holder is clean and free of chips before seating the shank, and confirm runout with a dial indicator before production use. Do not exceed the manufacturer-rated speeds and feeds for cobalt tooling in the material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eSeries\u003c\/strong\u003e: 541\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.75 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\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: 5411008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731639238962,"sku":"5411008","price":102.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3fb947082e4cdd448ce2087143e4e66_3e333c95-1723-4763-a135-40951c34b2c7.jpg?v=1788733440","url":"https:\/\/voomisupply.com\/products\/osg-5411008-square-end-mill-0-5in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
