Iscar 3398329 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The ISCAR 3398329 is a single-end square end mill designed for precision milling operations in metalworking and machining applications. Built from submicron-grade solid carbide, it delivers rigidity and wear resistance required for high-speed cuts in ferrous and non-ferrous materials. The tool features a TiAlCN coating that reduces friction and extends tool life in demanding cutting conditions. With a 5/8 inch cutting diameter, 1-3/4 inch length of cut, and a 38-degree helix angle, this end mill is suited for slotting, profiling, and peripheral milling where consistent chip evacuation and edge stability are critical. It is sold and installed as a single unit.

This end mill is used in CNC machining centers and manual vertical mills across job shops, production facilities, and tool-and-die operations. The variable index geometry reduces chatter during full-width and deep-wall cuts, making it appropriate for medium to high material removal rate applications. It is installed by machinists and CNC operators working with steel, stainless, cast iron, and similar materials where a coated carbide tool is the preferred choice over high-speed steel alternatives.

Key Features

• Submicron-grade solid carbide construction for rigidity and extended tool life
• TiAlCN coating reduces heat and friction in demanding cutting applications
• 38-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Variable index flute spacing minimizes chatter and vibration during milling
• Right-hand cut and right-hand spiral flute direction for standard CNC and manual mill setup
• Center-cutting capable, allowing plunge entry into workpiece material

Compatibility

Designed for use in standard 5/8 inch collets or end mill holders on CNC machining centers and manual vertical mills. Consult machine spindle and holder specifications before installation to confirm runout tolerance and holding force requirements.

Installation Notes

This tool is installed by qualified machinists or CNC operators. Before mounting, ensure the spindle is fully stopped and the machine is in a safe, locked-out state. Seat the 5/8 inch shank fully in a clean, properly torqued collet or end mill holder to minimize runout. Do not exceed the tool manufacturer's recommended cutting parameters for the workpiece material and depth of cut.
