It features a 0.3543 inch mill diameter, a 0.8661 inch length of cut, and a 0.3937 inch shank diameter. The two-flute, spiral-flute design runs at a 30-degree helix angle, promoting efficient chip evacuation and reduced cutting forces. A TiAlN coating provides thermal resistance and extended tool life in ferrous and hardened materials. This end mill is built for right-hand cut and right-hand flute direction, and is center-cutting for plunge capability. Machinists and CNC operators in job shops and production environments are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThe OSG 402-354311 is suited for slot milling, peripheral milling, and light plunge operations on ferrous metals, alloy steels, and hardened materials where coating performance matters. Its regular-length geometry and micrograin carbide construction make it a reliable choice for precision work on CNC machining centers and manual mills requiring a 10 mm shank. The 30-degree helix provides a balance between cutting aggressiveness and surface finish quality in medium-hardness materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for thermal protection and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eTwo-flute configuration suited for slot milling and applications requiring chip clearance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral geometry for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series 402 OSG square end mill for use in standard CNC machining centers and manual mills accepting a 0.3937 inch (10 mm) straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using an appropriate collet or end mill holder rated for the 0.3937 inch shank diameter. Ensure the spindle and tool holder are clean and free of debris before seating the tool. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates carbide wear and can cause breakage. Follow machine manufacturer guidelines for speeds and feeds appropriate to TiAlN-coated carbide tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3543 inches (9 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8661 inches (22 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70 mm\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\/Finish\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\u003eSeries\u003c\/strong\u003e: 402\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 x 0.75 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 402-354311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738895647026,"sku":"402-354311","price":69.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49f68c9fbd7a60e2b94f993fdfc63c43_054685b3-c233-4303-9622-22f78d6eb40f.jpg?v=1788806362","url":"https:\/\/voomisupply.com\/products\/osg-402-354311-square-end-mill-0-3543-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
