Built from 3% vanadium high speed steel, it delivers good wear resistance and edge retention across a range of ferrous and non-ferrous materials. The 1\/8 inch cutting diameter pairs with a 3\/8 inch shank, a 3\/8 inch length of cut, and a 2-5\/16 inch overall length. Two spiral flutes with a 30-degree helix angle promote chip evacuation and reduce cutting forces. The centercutting geometry allows plunge entry, making it suitable for slot milling, profile work, and light pocket milling without a pre-drilled start hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard CNC machining centers, knee mills, and manual mills equipped with a collet or end mill holder sized for a 3\/8 inch shank. The regular-length configuration and small 1\/8 inch diameter make it well suited for finishing passes, narrow slot cutting, detail work, and engraving-style profiles in steel, aluminum, brass, and plastics. It is sold as a single unit and is commonly stocked by tool cribs supplying general machining, toolroom, and maintenance operations.\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 HSS\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle spiral flutes promote efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for regrinding and general-purpose use\u003c\/li\u003e\n  \u003cli\u003eRegular-length series 573 profile balances reach and rigidity at small diameters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any standard milling machine or machining center with a collet, ER chuck, or end mill holder accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a clean, properly sized collet or end mill holder to ensure concentricity and minimize runout, which is especially critical at 1\/8 inch diameter. Ensure the machine spindle is fully stopped and powered down before inserting or removing the tool. Follow shop speeds-and-feeds guidelines appropriate to the workpiece material and depth of cut. At small diameters, reduce feed rate and depth of cut incrementally to avoid tool deflection or breakage.\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: 2\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\u003eEnd Mill Material\u003c\/strong\u003e: Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 3% Vanadium\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: 573\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 5730100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752724562226,"sku":"5730100","price":38.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae4e56bee49b47f6e319bb124bc231c0.jpg?v=1788929951","url":"https:\/\/voomisupply.com\/products\/osg-5730100-square-end-mill-1-8-in-2-flute-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
