Built from 3% vanadium high speed steel, this end mill delivers improved wear resistance compared to standard M2 HSS tooling. The 1\/8 inch cutting diameter and 3\/8 inch length of cut make it well suited for slotting, peripheral milling, and light profiling operations in smaller workpieces. The 30-degree helix angle promotes efficient chip evacuation while reducing cutting forces, and the centercutting geometry allows direct plunge entry without a pre-drilled start hole. Machinists and tool room operators on manual mills or CNC machining centers commonly specify this series for precision work.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits applications in job shops, tool rooms, and production environments where consistent performance from HSS tooling is required. The 3\/8 inch shank diameter seats in standard ER or end mill holders, and the 2-5\/16 inch overall length suits typical short-reach setups. Right-hand cut with right-hand spiral flutes is the standard configuration for conventional and climb milling on vertical machining centers. The uncoated finish is appropriate for use with cutting fluid or on materials where coated tooling is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3% vanadium high speed steel construction for improved wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration for improved surface finish and feed rate capability in finishing cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute spiral for standard milling setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for flood coolant or cutting oil applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production end mill for use in any machine tool accepting a 3\/8 inch straight shank, including vertical machining centers, knee mills, and manual milling machines with ER collet chucks or set-screw end mill holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill from the holder. Verify holder runout with a dial indicator before beginning a cut, as excessive runout will reduce tool life and surface finish quality. Consult the machine manufacturer and applicable OSHA machine guarding requirements before operating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 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: Vanadium High Speed Steel (3% Vanadium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/16 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\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\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: 5740100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749595578674,"sku":"5740100","price":38.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/867ed8521b7939e8ee20b78550b9b241.jpg?v=1788908102","url":"https:\/\/voomisupply.com\/products\/osg-5740100-square-end-mill-1-8-in-4-flute-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
