Gws 314709 Square End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The GWS 314709 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineered plastics. With a 3/8-inch cutting diameter, a 1/2-inch length of cut, and a 37-degree helix angle, it delivers aggressive material removal while maintaining edge stability. The zirconium nitride (ZrN) finish reduces friction and extends tool life in high-speed applications. Three flutes provide a balance between chip evacuation and surface finish quality. The upcut flute geometry pulls chips away from the workpiece, keeping the cutting zone clear. This end mill suits machinists and toolroom professionals working on CNC mills or manual knee mills.

The 314709 fits standard 3/8-inch collets and tool holders, making it a direct drop-in for most vertical and horizontal milling setups. It is centercutting, so it can be plunged directly into the workpiece without a pilot hole. The right-hand cut and right-hand flute configuration is the most common orientation for conventional and climb milling on CNC machining centers. Typical applications include slotting, profiling, and peripheral milling in production and prototype environments. This is a Series 2030 tool from GWS.

Key Features

• 3/8-inch cutting diameter with 1/2-inch length of cut for controlled engagement depth
• Solid carbide construction for rigidity and heat resistance
• ZrN (zirconium nitride) coating reduces friction and improves tool longevity
• 37-degree helix angle promotes efficient chip flow and smooth cutting action
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Upcut right-hand flute geometry suits standard CNC and manual milling setups

Compatibility

Designed for use with standard 3/8-inch collets and end mill holders on CNC machining centers and manual milling machines. Verify spindle speed and feed rate parameters against the workpiece material before use.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down the spindle and confirm the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the collet or tool holder and torque the retention hardware to the tool holder manufacturer's specification. Inspect the cutting edges for chips or coating damage before first use.
