Iscar 3401307 Square End Mill 5/8 in 4 Flute Carbide

Product Description

The ISCAR 3401307 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 5/8 inch (0.6250 inch) cutting diameter, a 3/4 inch length of cut, and a 4-flute configuration with a 38-degree helix angle. The tool carries a TiAlCN coating for increased heat and wear resistance. With a variable index geometry and right-hand cutting and flute direction, it is suited for aggressive material removal while maintaining dimensional accuracy. This end mill is installed and operated by machinists and CNC tooling technicians in job shop and production environments.

This end mill is built for milling ferrous and non-ferrous metals in both manual and CNC machining centers. The 5/8 inch shank diameter matches standard ER and side-lock toolholders common in vertical machining centers. The single-end, center-cutting design allows for plunge entry and peripheral milling in a single setup. Submicron carbide grade construction supports use in demanding applications where tool life and edge stability are critical. Typical uses include slotting, profiling, and pocket milling on steel, stainless, and alloy workpieces.

Key Features

• Solid carbide construction in submicron material grade for improved hardness and edge retention
• TiAlCN coating provides thermal barrier and reduces built-up edge in ferrous applications
• 38-degree helix angle promotes efficient chip evacuation and smooth surface finish
• Variable index flute spacing reduces harmonic vibration during high-feed passes
• Center-cutting design enables direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand spiral flute direction for standard spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 5/8 inch bore toolholders on CNC and manual vertical machining centers.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before initiating a cut, and confirm feeds and speeds are appropriate for the workpiece material and depth of cut.
