Built from 3% vanadium high speed steel, it delivers solid wear resistance and edge retention in ferrous and non-ferrous materials without the need for a coating. The cutter measures 9\/32 inch (0.2813 inch) in diameter with an 11\/16 inch (0.6875 inch) length of cut, a 3\/8 inch shank diameter, and a 2-1\/2 inch overall length. The 30-degree spiral helix promotes efficient chip evacuation and smooth cutting action. This is an uncoated, regular-length end mill suited for machinists working in job shops, tool rooms, or maintenance environments.\u003c\/p\u003e\u003cp\u003eThe OSG 5740600 is intended for use in vertical milling machines, CNC machining centers, and manual knee mills where a standard right-hand cut, right-hand flute end mill is required. Its centercutting geometry allows it to be plunged directly into a workpiece, making it suitable for slot milling, profiling, and pocket entry operations. The regular-length design provides rigidity appropriate for general-purpose work rather than deep-reach or extended-neck applications. Machinists working with steel, aluminum, cast iron, and similar materials will find this a dependable everyday tool for medium-duty cutting tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3% vanadium high speed steel construction for improved wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e4-flute geometry for improved surface finish and feed rate capability in ferrous materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eUncoated finish — suitable for re-sharpening in a tool room environment\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute — standard configuration for conventional milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-stock square end mill for use in any machine tool spindle accepting a 3\/8 inch straight shank, including ER collet systems, end mill holders, and Weldon-style holders of the appropriate bore size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the machine spindle is fully powered down and locked out before changing tooling. The shank should be inserted to the full recommended engagement depth in the holder to minimize runout and prevent pullout under cutting loads. Follow the machine tool manufacturer and holder manufacturer specifications for clamping torque and projection length. Inspect the cutting edges for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/32 inch (0.2813 inch)\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: Vanadium High Speed Steel (3% Vanadium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 11\/16 inch (0.6875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\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\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: 574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 5740600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746227519794,"sku":"5740600","price":41.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/691ecbc2d609aea9c8a5a319ac056b74.jpg?v=1788867367","url":"https:\/\/voomisupply.com\/products\/osg-5740600-square-end-mill-9-32-in-4-flute-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
