Built from 3% vanadium high speed steel with a TiCN coating, it delivers improved wear resistance and heat tolerance compared to standard HSS tooling. The cutter features a 11\/32 inch (0.3438 inch) diameter, a 3\/4 inch length of cut, and a 4-flute spiral geometry with a 30-degree helix angle. Centercutting capability allows the tool to plunge directly into the workpiece. It is a single-end, right-hand cut, right-hand flute configuration in the OSG Series 574 lineup, suitable for CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is used in production and job-shop environments for slotting, profiling, and peripheral milling. The 3\/8 inch shank diameter fits standard ER collet chucks and end mill holders common to vertical machining centers and knee mills. The regular-length geometry makes it well-suited for shallow to medium-depth cuts in steel, alloy steel, cast iron, and similar materials where TiCN coating provides a practical performance advantage over uncoated tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3% vanadium high speed steel construction for improved toughness and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating extends tool life in ferrous materials by reducing friction and heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration balances metal removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — standard orientation for conventional CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style cutting tool for use in standard 3\/8 inch end mill holders, ER collet chucks, and Weldon-style holders on vertical machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the holder and torque the set screw or collet nut to the holder manufacturer's specification. Inspect the cutting edges for chips or damage before each use; a damaged TiCN coating or chipped flute indicates the tool should be replaced rather than reground.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/32 inch (0.3438 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 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: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eSeries\u003c\/strong\u003e: 574\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\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: 5740808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732952482098,"sku":"5740808","price":52.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7a0cd0e84b669f7b72b3d6737f3ddaa.jpg?v=1788749482","url":"https:\/\/voomisupply.com\/products\/osg-5740808-square-end-mill-11-32-in-4-flute-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
