Iscar 3401333 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The ISCAR 3401333 is a single-end, solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 3/4 inch diameter cutting head with four flutes and a 38-degree helix angle, delivering an efficient balance of chip evacuation and surface finish. The tool carries a TiAlCN coating to extend tool life under elevated cutting temperatures and abrasive conditions. With a 1-5/8 inch length of cut and 4 inch overall length, it is suited for moderate-depth slotting, profiling, and peripheral milling operations. This end mill is installed and run by machinists and tool-and-die professionals in shop environments.

This end mill is used in machining centers and manual milling machines for applications in general metalworking, die and mold work, and precision part production. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. The variable index geometry helps reduce harmonic chatter during cuts, making it appropriate for both roughing and finishing passes at appropriate feed and speed parameters. Submicron carbide grain construction supports rigidity and edge retention in demanding cuts.

Key Features

• 3/4 inch cutting diameter with matching 3/4 inch shank diameter for direct collet or end mill holder mounting
• TiAlCN coating for heat resistance and extended tool life in ferrous materials
• 38-degree helix angle promotes smooth chip flow and reduced cutting forces
• Variable index flute spacing reduces chatter and vibration during milling
• Center-cutting capability allows direct plunge entry into workpiece material
• Submicron carbide substrate for superior hardness and edge retention

Compatibility

Designed as a solid carbide square end mill for use in standard 3/4 inch collets, end mill holders, or hydraulic chucks on CNC and manual milling machines.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Verify the holder bore and collet size match the 3/4 inch shank diameter before tightening. Follow machine tool manufacturer guidelines for proper tool overhang and runout tolerances to prevent premature tool wear or breakage.
