Built from micrograin carbide and finished with a titanium carbonitride (TiCN) coating, it delivers hardness and wear resistance suited for ferrous and non-ferrous materials. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and stable cutting at moderate to high feed rates. At 0.3438 inches in diameter with a 1-inch length of cut and 2-1\/2 inch overall length, this end mill fits compact tooling setups while maintaining rigidity. Centercutting geometry allows direct plunge entry without a pre-drilled hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual knee mills for peripheral milling, slotting, and plunge cutting. The 3\/8-inch shank diameter is compatible with standard ER collet chucks, end mill holders, and Weldon-style tool holders common in production and job shop environments. It is appropriate for finishing and semi-finishing passes on steel, stainless, aluminum, and similar machinable alloys. The regular length classification and non-extended reach profile make it well suited for general-purpose cavity work and contour milling where rigidity is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and reduces built-up edge in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral with 30-degree helix for balanced chip load and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without pilot hole\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.001 inches for consistent fitment\u003c\/li\u003e\n  \u003cli\u003eShank diameter tolerance of +0.00000 \/ -0.0005 inches for precise tool holder seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production tooling option for Series 404 OSG square end mills with a 3\/8-inch shank diameter.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Apply appropriate clamping torque per the tool holder specification to avoid slippage without damaging the shank. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear and reduce surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\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\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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: TiCN\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.0005 inches\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: 404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: 404-343808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728443572530,"sku":"404-343808","price":68.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e37141def6895b84d4197c841334fcd.jpg?v=1788691263","url":"https:\/\/voomisupply.com\/products\/osg-404-343808-square-end-mill-11-32-in-4-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
