With a 0.375-inch mill diameter, 0.875-inch length of cut, and 3-inch overall length, this tool is built for tight-tolerance profiling, slotting, and peripheral milling. The DLC-IGUSS coating provides enhanced wear resistance and reduced friction at the cutting edge. Three flutes with a variable helix angle improve chip evacuation and reduce chatter, making this end mill well suited for demanding material removal applications. A licensed machinist or CNC operator typically selects and installs this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is configured for right-hand cut with right-hand flute direction and is centercutting, allowing plunge entry into the workpiece. The 3\/8-inch shank diameter fits standard collets and end mill holders on vertical machining centers, CNC mills, and manual knee mills. The variable helix geometry helps manage vibration during long tool engagement passes, making it a practical choice for both roughing and semi-finishing cuts in steel, stainless, and similar alloys. Individual packaging with a minimum order quantity of 1 makes it easy to replace a single tool as needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eDLC-IGUSS coating for reduced friction and improved wear resistance\u003c\/li\u003e\n  \u003cli\u003eVariable helix angle reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill setups\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances chip clearance with cutting edge strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement end mill for use in standard 3\/8-inch collets and end mill holders on CNC machining centers and manual vertical mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: DLC-IGUSS\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.82 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 88300409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748502143282,"sku":"88300409","price":165.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da66ab358d2b755df23bb309403c2093_c3e9ede1-ac10-44c8-959b-7427f89afed0.jpg?v=1788894534","url":"https:\/\/voomisupply.com\/products\/osg-88300409-square-end-mill-3-8-inch-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
