It features a 9\/32 inch (0.2813 inch) cutting diameter, a 3\/4 inch length of cut, and a 5\/16 inch shank diameter with a 2-1\/2 inch overall length. The tool carries a TiAlN finish that improves heat resistance and extends tool life in ferrous and hardened material applications. Two spiral flutes at a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. Centercutting geometry allows plunge milling in addition to standard peripheral and slot milling. This end mill is intended for use by machinists and toolroom technicians operating CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThe 402-281211 is suited for slot milling, profiling, and light pocket milling in steel, stainless steel, cast iron, and similar materials. The regular-length body and right-hand cut with right-hand flute configuration make it a standard-fit tool for general-purpose horizontal and vertical milling setups. The micrograin carbide substrate provides edge retention in demanding cuts. It is a single-end tool from OSG Series 402, typically used in production machining, tool and die work, and precision fabrication shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for improved thermal resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill compatibility\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry suited for slotting, profiling, and light pocketing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in standard CNC machining centers, vertical mills, and manual milling machines that accept a 5\/16 inch shank diameter toolholder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet or toolholder. Verify the shank is fully seated and the collet is torqued to the toolholder manufacturer specification before operation. Inspect the cutting edges for chips or wear before each use, as carbide tools are brittle and can fracture if re-run with damaged geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/32 inch (0.2813 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: 5\/16 inch (0.3125 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 402\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: 402-281211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741344399666,"sku":"402-281211","price":61.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80739c027993e29e7bae621a478e7b93.jpg?v=1788830903","url":"https:\/\/voomisupply.com\/products\/osg-402-281211-square-end-mill-9-32-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
