Iscar 3401305 Square End Mill 1/2 in 4 Flute Carbide

Product Description

The ISCAR 3401305 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining environments. It features a 1/2 inch cutting diameter, a 3 inch length of cut, and a 6 inch overall length. The four-flute, right-hand spiral design with a 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiAlCN coating provides thermal resistance and extended tool life in high-speed or dry machining applications. This end mill is installed and operated by machinists and CNC tooling professionals in production and job shop settings.

This end mill is suited for general-purpose and high-performance milling in ferrous and non-ferrous materials. The variable index flute geometry reduces harmonic vibration during aggressive cuts, making it appropriate for both roughing and finishing passes. The single-end configuration with a 1/2 inch shank diameter fits standard collet chucks and end mill holders used in vertical machining centers and CNC mills. Submicron carbide grade construction contributes to edge retention under demanding cutting conditions.

Key Features

• Solid carbide construction in submicron material grade for edge retention and rigidity
• TiAlCN coating for thermal protection and extended tool life in dry or high-speed cutting
• 38-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Variable index flute spacing reduces vibration and chatter during aggressive milling passes
• Four flutes, right-hand cut and right-hand spiral for standard CNC mill compatibility
• Center-cutting capability allows plunge entry without a pre-drilled pilot hole

Compatibility

Designed as a direct-fit replacement for standard 1/2 inch shank end mill holders, collet chucks, and hydraulic toolholders used in CNC vertical machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Use a calibrated torque wrench when tightening collet nuts or set screws to the toolholder manufacturer specifications. Verify runout with a dial indicator after installation before initiating a cutting program.
