Built from micrograin carbide, this double-end tool delivers consistent performance across a range of ferrous and non-ferrous materials. The TiAlN coating improves heat resistance and extends tool life at elevated cutting speeds. With 4 flutes and a right-hand helix and cutting direction, it produces clean, accurate cuts in both roughing and finishing passes. The 3\/8-inch shank diameter and 3.0625-inch overall length make it compatible with standard toolholders used in CNC and manual milling setups.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for production and job-shop environments where consistent dimensional accuracy is required. The double-end design provides two cutting ends per tool, extending usable tool life before replacement. It is typically installed and used by machinists, tool-and-die makers, and CNC operators working on milling machines and machining centers. The TiAlN coating makes it well-suited for dry or semi-dry cutting conditions at higher spindle speeds.\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 improved thermal resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e4-flute configuration balances chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard milling operations\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter fits standard collets and toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production end mill for use in CNC machining centers and manual milling machines that accept a 3\/8-inch shank diameter toolholder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or CNC operator familiar with proper toolholder torque procedures and runout tolerances. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the collet or toolholder. Inspect both cutting ends for chipping or wear before use. Follow machine manufacturer guidelines for maximum RPM and feed rate recommendations appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches\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\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\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: 444-125011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743029821746,"sku":"444-125011","price":91.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e5a1e791596cc0b6d83e66bb0540288.jpg?v=1788841775","url":"https:\/\/voomisupply.com\/products\/osg-444-125011-square-end-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
