Iscar 3401303 Square End Mill 0.5 Inch 4 Flute Solid Carbide

Product Description

The ISCAR 3401303 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 0.5 inch cutting diameter, a 2.5 inch length of cut, and a 5 inch overall length, with a 0.5 inch shank diameter for secure tool holder engagement. The four-flute spiral design runs a 38-degree helix angle, and the TiAlCN finish provides thermal and wear resistance at elevated cutting speeds. The submicron grain carbide substrate supports edge retention in hardened steels, stainless alloys, and high-temp materials. This tool is centercutting, allowing direct plunge entry without a pre-drilled hole.

The 3401303 is suited for milling operations in job shops, production machining cells, and toolrooms handling ferrous and non-ferrous materials. The variable index geometry helps reduce harmonic chatter during slotting, profiling, and finishing passes. Right-hand cut and right-hand flute configuration is standard for conventional CNC vertical machining center setups. It is typically installed by machinists and CNC operators working in industries requiring tight dimensional tolerances on milled features.

Key Features

• Solid carbide construction with submicron grain substrate for extended tool life
• TiAlCN coating for heat resistance and reduced tool wear at high surface footage
• 38-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Variable index flute spacing reduces chatter and vibration during aggressive cuts
• Centercutting design enables direct plunge milling without a pilot hole
• Right-hand cut, right-hand flute configuration compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 0.5 inch collet chucks, end mill holders, and shrink-fit tool holders on CNC vertical or horizontal machining centers.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine spindle before changing tooling. Seat the shank fully into the tool holder and torque retention screws or collet nuts per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cutting cycle to avoid premature tool failure or dimensional error.
