Iscar 3398530 Square End Mill 0.5in 5 Flute Solid Carbide

Product Description

The ISCAR 3398530 is a solid carbide square end mill designed for high-performance milling in a wide range of metalworking and machining applications. With a 0.5 inch diameter, five flutes, and a 38-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action across ferrous and non-ferrous materials. The TiAlCN coating provides enhanced heat resistance and surface hardness, extending tool life in demanding cutting conditions. Centercutting capability allows direct plunge operations, adding versatility for profiling, slotting, and pocketing tasks. This tool is intended for use by machinists and CNC operators working on manual mills, machining centers, and similar equipment.

The 3398530 is suited for general-purpose and precision milling in job shops, production facilities, and toolrooms. Its right-hand cutting and right-hand flute direction make it compatible with standard CNC and manual milling setups. The 0.5 inch shank diameter fits common tool holders and collets used in vertical and horizontal machining centers. The 1.25 inch length of cut supports moderate-depth passes in steel, stainless steel, aluminum, and similar workpiece materials. Variable index geometry helps reduce chatter and vibration during cuts, improving surface finish and dimensional consistency.

Key Features

• 0.5 inch mill diameter with 0.5 inch shank diameter for standard toolholder compatibility
• Five-flute design with 38-degree helix angle for efficient chip flow and improved feed rates
• TiAlCN coating for elevated temperature resistance and extended tool life
• Centercutting construction allows direct plunge milling and full-slot operations
• Variable index flute spacing reduces harmonic vibration and chatter during cutting
• Submicron carbide grade provides toughness and wear resistance in demanding materials

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 0.5 inch collets, end mill holders, and shrink-fit toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is secured in a properly rated toolholder before tightening. Follow the toolholder manufacturer torque specifications and verify runout with a dial indicator before commencing cuts. Inspect the cutting edges for damage before each use and replace the tool if chipping or wear is evident.
