The cutter features a 15\/64 inch (0.2344 inch) mill diameter with a 3\/4 inch length of cut and a 1\/4 inch shank diameter. Overall length is 2-1\/2 inches. Four spiral flutes with a 30-degree helix angle provide efficient chip evacuation and smooth cutting action. The centercutting geometry allows plunge entry into the workpiece. This end mill is manufactured from micrograin solid carbide and left uncoated, making it well suited for applications where coating compatibility or surface finish tolerance is a primary concern. Machinists and tool-and-die shops are the primary users.\u003c\/p\u003e\u003cp\u003eThe OSG 404-2344 is suited for light to medium milling operations including slotting, profiling, and plunge cutting. The regular-length body fits standard toolholders and collet chucks with a 1\/4 inch bore. Right-hand cut and right-hand flute configuration is compatible with conventional CNC machining centers, knee mills, and manual milling machines. The uncoated micrograin carbide substrate performs reliably in ferrous and non-ferrous materials. This end mill ships as a single unit and is intended for professional machine shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/64 inch (0.2344 inch) mill diameter for precise, close-tolerance cuts\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications where bare carbide is preferred\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard addition for 1\/4 inch shank toolholders and collet chucks used in CNC machining centers and manual milling machines requiring a 15\/64 inch square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing the end mill from the toolholder or collet chuck. Ensure the collet bore matches the 1\/4 inch shank diameter before tightening. Inspect the cutting edges and shank for damage before each use; carbide end mills are brittle and should not be dropped or used in worn toolholders that allow runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 15\/64 inch (0.2344 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: 404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 404-2344\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734727852338,"sku":"404-2344","price":42.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e339aa3f5ac09bbab3fef912e46d9d0.jpg?v=1788766183","url":"https:\/\/voomisupply.com\/products\/osg-404-2344-square-end-mill-15-64-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
