Gws 314493 Square End Mill 5/32 in 3 Flute Solid Carbide Zrn

Product Description

The GWS 314493 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 5/32 inch (0.1563 inch) cutting diameter, a 5/16 inch length of cut, and a 3/16 inch shank diameter with a 2 inch overall length. The three-flute geometry paired with a 37-degree helix angle and ZrN (zirconium nitride) finish promotes efficient chip evacuation and improved tool life in ferrous and non-ferrous materials. The upcut flute design and centercutting capability make this end mill suitable for both peripheral and plunge milling operations. Weighing 0.04 pounds, it is a compact, high-performance cutting tool for CNC machining centers and manual mills.

This end mill is well suited for light to moderate material removal in precision machining environments, including job shops, tool rooms, and production facilities. The solid carbide construction handles tighter tolerances and harder workpiece materials compared to HSS alternatives. The right-hand cut and right-hand flute configuration is the standard orientation for most vertical milling setups. The ZrN coating provides additional surface hardness and lubricity, making it a practical choice for dry or semi-dry cutting conditions. It is part of the GWS Series 2030 lineup.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• ZrN finish increases surface hardness and reduces friction during cutting
• 37-degree helix angle improves chip flow and reduces cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• Upcut, right-hand flute with right-hand cut for standard CNC and manual mill compatibility
• 3-flute geometry balances chip clearance and surface finish in a small-diameter tool

Compatibility

Designed as an OEM-style replacement or direct-fit cutting tool for standard 3/16 inch collet or end mill holder setups on vertical milling machines and CNC machining centers requiring a 5/32 inch square end mill.

Installation Notes

This end mill is installed by a machinist or CNC setup technician using a compatible collet, shrink-fit holder, or end mill holder sized for a 3/16 inch shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout with a dial indicator after installation to maintain dimensional accuracy. Follow the machine manufacturer and tooling guidelines for proper torque on collet nuts.
