The GWS 313039 is a solid carbide square end mill designed for precise milling operations in metal, composites, and other hard materials. It features a 1/4 inch cutting diameter and a 3/4 inch length of cut, making it well suited for slotting, profiling, and peripheral milling in tight-tolerance applications. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. A ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in demanding cutting conditions. This end mill is installed and operated by machinists and CNC tool-and-die professionals working with manual mills or CNC machining centers.
The GWS 313039 is intended for single-end milling operations in shop and production environments. Its 2-flute geometry is particularly effective in aluminum, non-ferrous metals, and softer alloy steels where chip clearance is a priority. The 2.5 inch overall length and 1/4 inch shank diameter suit it for standard collet chucks and end mill holders commonly found in vertical machining centers and knee mills. Right-hand cutting and right-hand flute direction are standard for conventional CNC and manual mill setups.
Designed as a standard replacement or stock tooling option for 1/4 inch collet chucks and end mill holders used in CNC machining centers, knee mills, and manual vertical mills requiring a 1/4 inch shank square end mill.
This end mill is installed by machinists using a compatible collet chuck or end mill holder rated for 1/4 inch shank tooling. Ensure the machine spindle is fully powered down and locked out before changing tooling. Verify collet and holder cleanliness and proper torque on retention hardware per the machine tool manufacturer specifications. Do not exceed the recommended depth of cut or feed rate for the workpiece material and tool diameter.
