Built from submicron-grade solid carbide and coated with TiAlCN for heat and wear resistance, this tool handles high-speed and high-feed applications where surface finish and tool life both matter. It runs a 3\/4-inch cutting diameter with a 1-5\/8-inch length of cut, a 38-degree right-hand spiral helix, and a variable index flute geometry that reduces chatter during aggressive passes. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill suits vertical and horizontal machining centers running 3\/4-inch-diameter toolholders. The 5-flute configuration supports higher feed rates compared to standard 4-flute designs, making it well suited for finishing and semi-finishing passes on steel, stainless, and hardened alloys. The right-hand cut and right-hand flute direction are standard for conventional CNC milling setups. The 4-inch overall length fits most standard-depth applications without requiring extended-reach holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiAlCN coating improves heat resistance and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e5-flute design supports higher feed rates compared to 4-flute alternatives\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during cutting\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle optimizes chip evacuation and cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry into workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 3\/4-inch shank end mill toolholders used in CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine in a locked-out state per applicable shop safety procedures. Use a calibrated torque wrench and the appropriate collet or set-screw holder for 3\/4-inch shank tooling. Inspect the shank and collet bore for debris or wear before seating the tool. Verify runout with a dial indicator after installation before initiating a cutting pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-5\/8 inches (1.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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: 5\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 Type\u003c\/strong\u003e: Single End\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 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\u003eWeight\u003c\/strong\u003e: 1.15 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3398532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728508420402,"sku":"3398532","price":288.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f4db0e48a1997cfe5dd176c66a02da0_12a332ad-5cd2-4225-a8ed-b082a4e3df80.jpg?v=1788692376","url":"https:\/\/voomisupply.com\/products\/iscar-3398532-square-end-mill-3-4-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
