It features a 1\/2 inch cutting diameter, a 1-1\/2 inch length of cut, and a 4 inch overall length with a matching 1\/2 inch shank diameter. The tool carries a TiAlCN coating for improved wear resistance and heat performance at elevated cutting speeds. Four flutes with a 38-degree helix angle and a variable index configuration help reduce chatter and improve surface finish. Center-cutting geometry allows plunge entry. Right-hand cut and right-hand flute direction are standard. This end mill is installed and run by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eSuited for slotting, profiling, and pocketing operations in ferrous and non-ferrous materials. The submicron carbide grade supports consistent performance in hardened steels, alloy steels, and stainless steel applications. The spiral flute design promotes chip evacuation in both conventional and climb milling passes. Single-end configuration makes this a direct consumable replacement in standard end mill toolholders with a 1\/2 inch bore. Typical applications include die and mold work, aerospace component machining, and general precision part production where tight tolerances and repeatable tool life are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in submicron grain material grade for extended tool life\u003c\/li\u003e\n  \u003cli\u003eTiAlCN coating for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle with variable index for chatter reduction\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable for direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute direction\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration balances chip load and surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct replacement end mill for standard 1\/2 inch bore end mill toolholders, collet chucks, and shrink-fit holders used in CNC machining centers and manual mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Insert the shank fully into the toolholder to the recommended gauge line and torque the retention mechanism per the toolholder manufacturer specification. Inspect the cutting edges and coating condition before each setup to confirm the tool is fit for use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (4.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 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: 38 degrees\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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlCN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3401299\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51739076788530,"sku":"3401299","price":115.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/458e4b8b95217f1bc9f8c1adcf597f66.jpg?v=1788809002","url":"https:\/\/voomisupply.com\/products\/iscar-3401299-square-end-mill-1-2-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
