Gws 1034021 Square End Mill 5/16 in 4 Flute Solid Carbide

Product Description

The GWS 1034021 is a solid carbide square end mill designed for precision milling in demanding machining applications. Built from submicron-grade carbide and coated with FX7 for extended tool life and heat resistance, this single-end mill features a 5/16-inch cutting diameter and a 1/2-inch length of cut. The 33-degree variable helix geometry reduces chatter and improves chip evacuation during aggressive cuts. With four flutes and both variable helix and variable index construction, it delivers smooth surface finishes and consistent performance in ferrous and non-ferrous materials.

This end mill suits CNC machining centers and manual mills in job shops, tool rooms, and production environments. It is well suited for slot milling, profiling, and contouring operations where tight tolerances and surface finish quality matter. The 5/16-inch shank diameter matches common collet sizes, and the 2-inch overall length fits standard short-reach setups. Machinists and CNC operators working in aerospace, automotive, and general metalworking will find this tool fits a wide range of light to medium-duty cutting tasks.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance
• FX7 coating for improved lubricity, heat resistance, and extended tool life
• Variable helix and variable index design reduces harmonics and chatter
• Four flutes with right-hand cut and right-hand flute direction
• Center-cutting capable for plunge entry
• 5/16-inch shank diameter for compatibility with standard collet systems

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling machines accepting a 5/16-inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with end mill tooling and machine safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Secure the shank fully within the collet or holder to the manufacturer-recommended engagement depth to prevent pullout. Verify runout with a dial indicator before initiating a cut.
