Built from M42 cobalt high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, it delivers extended tool life and thermal resistance compared to standard HSS tooling. At 0.5 inches in diameter with a 1.25-inch length of cut and 3.25-inch overall length, it fits a wide range of vertical and horizontal milling operations. The 30-degree helix angle promotes smooth chip evacuation, and the centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. Installed by machinists and tool-and-die professionals in CNC and manual milling setups.\u003c\/p\u003e\u003cp\u003eThe 5411508 belongs to OSG Series 541, a regular-length single-end cobalt end mill line suited for general-purpose slot milling, peripheral milling, and profiling in ferrous alloys, stainless steel, and other tough materials. The 0.5-inch shank diameter matches standard R8, ER32, and side-lock holders common in VMC and manual knee-mill setups. With a right-hand cut and right-hand spiral, it is compatible with conventional milling machine spindle rotation. This tool is appropriate for job shops, production machining environments, and maintenance departments requiring reliable, repeatable material removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-flute geometry increases feed rate potential and improves surface finish compared to 4-flute designs\u003c\/li\u003e\n\u003cli\u003eM42 cobalt material grade provides superior heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive and tough alloy applications\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with single-end configuration for standard milling machine use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eOSG Series 541 regular-length single-end cobalt square end mill.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the holder and torque set screws or collet nuts per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to maximize tool life and surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 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: 3.25 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\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\u003eCutting 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\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: 541\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 5411508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733139456306,"sku":"5411508","price":110.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f484cb57434c04b62b1ccac89841045f.jpg?v=1788751775","url":"https:\/\/voomisupply.com\/products\/osg-5411508-square-end-mill-0-5in-6-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
