Gws 315147 Square End Mill 1/4 in 3 Flute Solid Carbide Zrn

Product Description

The GWS 315147 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. It features a 0.25-inch diameter with a 0.75-inch length of cut and a 3-flute geometry that balances chip evacuation with surface finish quality. The 37-degree helix angle promotes efficient cutting action and reduced vibration during operation. A ZrN (zirconium nitride) coating extends tool life and improves performance in non-ferrous and ferrous materials. This tool is installed and operated by machinists, toolmakers, and CNC operators working in job shop and production environments.

The 315147 is suited for slotting, profiling, and peripheral milling operations where a compact, short-flute end mill is appropriate. Its 0.25-inch shank diameter matches standard collets and tool holders in that size range. The 2.5-inch overall length keeps the tool rigid and minimizes deflection in applications where reach is not the primary requirement. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC milling setups. The submicron carbide grade supports use in demanding cuts where edge retention is critical.

Key Features

• 0.25-inch diameter with 0.75-inch length of cut for short, rigid milling setups
• 3-flute design balances chip clearance and finish quality
• 37-degree helix angle reduces cutting forces and vibration
• ZrN coating improves wear resistance and tool life
• Centercutting geometry allows plunge entry
• Submicron solid carbide grade for edge retention in hard materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 0.25-inch collet and shrink-fit tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or tool holder torqued to the tool holder manufacturer specification. Inspect the cutting edges and coating condition before each use and replace the tool if chipping or wear is observed.
