Gws 313927 Square End Mill 1/2 in 2 Flute Solid Carbide

Product Description

The GWS 313927 is a solid carbide square end mill designed for high-performance material removal in milling applications. Built from submicron-grade carbide and finished with a ZrN (zirconium nitride) coating, it handles demanding cutting conditions with improved wear resistance and surface finish. The 2-flute configuration with a 45-degree helix angle promotes efficient chip evacuation, and the extended reach geometry - with a 1-3/8 inch reach length and 5/8 inch length of cut - allows access in deeper pockets and slots. This is a right-hand cut, right-hand flute, single-end tool suited for use by machinists, tool-and-die professionals, and CNC operators.

The 313927 is well suited for slotting, profiling, and pocketing operations in ferrous and non-ferrous materials where a tight-tolerance square shoulder profile is required. The upcut flute geometry clears chips upward and away from the cut zone, reducing recutting and heat buildup. The 1/2 inch shank diameter fits standard ER and milling chuck toolholders commonly found on VMCs and manual knee mills. This tool is appropriate for both production shops and maintenance machining environments.

Key Features

• Submicron solid carbide substrate for rigidity and edge retention
• ZrN coating improves heat resistance and reduces built-up edge
• 45-degree helix angle promotes aggressive chip evacuation
• 2-flute design suited for slotting and pocketing operations
• Extended reach with 1-3/8 inch reach length for deep-feature access
• Centercutting geometry allows plunge entry

Compatibility

Designed as an OEM-style replacement or direct fitment for standard 1/2 inch shank milling chuck and ER collet toolholding systems used on CNC vertical machining centers and manual mills. Part of the GWS Series 2012 product line.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. The spindle must be fully stopped and the machine powered down before changing tooling. Use a properly sized ER collet or milling chuck torqued per the toolholder manufacturer specification. Inspect the shank and collet bore for chips or damage before seating the tool to ensure concentricity and prevent premature wear.
