With a 3\/4-inch cutting diameter and a 2-1\/4-inch length of cut, this single-end tool delivers the reach and rigidity needed for peripheral and slot milling in steel, stainless, and high-temp alloys. The submicron carbide grade provides excellent hardness and wear resistance. A TiAlCN coating adds thermal protection and reduces friction, extending tool life in high-speed applications. Licensed machinists and toolroom technicians are the primary installers and operators of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual knee mills performing roughing and finishing cuts on ferrous and non-ferrous workpiece materials. The 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. The variable index flute geometry reduces harmonic vibration during aggressive cuts, making it a practical choice for production environments where chatter control directly affects surface finish quality and dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch cutting diameter with 2-1\/4-inch length of cut for deep slot and peripheral milling\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral configuration with 38-degree helix for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eTiAlCN coating provides high-temperature resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade delivers superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces vibration and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/4-inch shank round end mill compatible with ER collet chucks, end mill holders, and hydraulic tool holders sized for 3\/4-inch shank tooling on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists familiar with rotating cutting tool safety. Ensure the tool holder bore is clean and free of debris before seating the shank, and torque the retention screw or collet nut to the tool holder manufacturer specification. Confirm spindle speed and feed rate parameters match the material being cut before engaging the tool. Never exceed the tool's rated depth of cut or operate with a damaged or chipped cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (2.25 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.75 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\/Finish\u003c\/strong\u003e: TiAlCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.44 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: 3398347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51733765849394,"sku":"3398347","price":298.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f4db0e48a1997cfe5dd176c66a02da0_e37e0ca7-7c25-47ae-9579-7b4577cf1c46.jpg?v=1788759048","url":"https:\/\/voomisupply.com\/products\/iscar-3398347-square-end-mill-3-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
