Iscar 3401301 Square End Mill 1/2 in 4 Flute Carbide

Product Description

The ISCAR 3401301 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 1/2 inch cutting diameter and 2 inch length of cut, this single-end tool delivers consistent performance in ferrous and non-ferrous materials. The 4-flute configuration with a 38-degree helix angle promotes efficient chip evacuation and surface finish quality. A TiAlCN coating adds thermal and wear resistance, extending tool life in demanding cutting conditions. The submicron carbide grade provides toughness and edge retention across a range of milling operations. This end mill is handled and installed by machinists and CNC tooling technicians in production and job shop environments.

This end mill suits general-purpose and high-performance milling tasks including slotting, peripheral milling, and contouring. The variable index geometry helps reduce harmonic vibration during cuts, making it effective in both light finishing passes and moderate material removal applications. The right-hand cutting and right-hand flute direction are standard for conventional CNC machining center setups. It is appropriate for use in vertical and horizontal machining centers across residential toolroom and commercial production environments.

Key Features

• Solid carbide construction in submicron grade for edge retention and toughness
• TiAlCN coating provides wear resistance and thermal protection in demanding cuts
• 38-degree helix angle promotes smooth chip flow and improved surface finish
• Variable index flute spacing reduces chatter and harmonic vibration
• Center-cutting design allows plunge entry into workpiece material
• Right-hand cut and right-hand spiral configuration for standard CNC setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 1/2 inch straight shank end mill holder or collet.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. The shank should be seated fully and securely in a matching 1/2 inch collet, end mill holder, or shrink-fit toolholder before operation. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Do not exceed the tool manufacturer recommended depth of cut or feed rate parameters for the workpiece material being machined.
