Gws 314690 Square End Mill 5/16 in 3 Flute Solid Carbide

Product Description

The GWS 314690 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering-grade materials. With a 5/16 inch cutting diameter and a 2-1/8 inch length of cut, this tool handles deep-reach slotting, profiling, and peripheral milling where shorter tools fall short. The submicron carbide grade provides the hardness and edge retention needed for demanding cutting conditions. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern. Licensed machinists and tool-and-die professionals are the primary users of this end mill in both manual and CNC milling setups.

This end mill is suited for use in vertical machining centers, knee mills, and CNC routers where a 5/16 inch shank is compatible with the collet or toolholder. The 4 inch overall length and extended 2-1/8 inch length of cut make it appropriate for deep cavity work, tall workpiece profiles, and hard-to-reach features. The Series 2030 designation places it within a defined product family from GWS. It is used in job shops, production facilities, and tool rooms where consistent chip evacuation and dimensional accuracy are required.

Key Features

• Solid carbide construction in submicron material grade for edge retention and rigidity
• 3 flutes with right-hand cut and right-hand flute direction for standard milling operations
• 37-degree helix angle promotes efficient chip evacuation in deep-reach cuts
• Centercutting design allows plunge entry directly into the workpiece
• Bright uncoated finish compatible with a wide range of workpiece materials
• Upcut flute geometry lifts chips away from the cutting zone

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC and manual milling machines accepting a 5/16 inch shank collet or end mill holder.

Installation Notes

Installation requires a clean, properly sized collet or end mill holder; contamination or wear in the toolholder will cause runout and premature tool failure. Always power down and lock out the machine spindle before changing tooling, following standard lockout/tagout procedures. Confirm collet torque to the machine manufacturer specification using the correct spanner wrench before initiating a cut. Do not exceed the tool's rated length of cut when setting axial depth of cut parameters.
