Gws 119348 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The GWS 119348 is a solid carbide square end mill designed for high-performance metal removal across a wide range of workpiece materials. With a 5/8 inch cutting diameter, 4 flutes, and a variable 38-degree helix angle, this single-end mill delivers improved chip evacuation and reduced chatter during demanding cuts. The nACRo coating adds heat and wear resistance, extending tool life in abrasive and high-temperature cutting conditions. It is intended for use by machinists and CNC operators working in job shops, production environments, and toolrooms where dimensional accuracy and surface finish matter.

This end mill is suited for milling operations on materials including high-temperature alloys, cast iron, stainless steel, non-ferrous metals, steel, and titanium, corresponding to material codes H, K, M, N, P, and S. With a 1-1/4 inch length of cut and 3-1/2 inch overall length, it handles standard-depth slotting, profiling, and peripheral milling applications. The right-hand cut and right-hand flute direction make it compatible with conventional CNC milling machine spindles. The Series 1030 designation identifies this as part of GWS's submicron carbide grade lineup for precision tooling applications.

Key Features

• 5/8 inch cutting diameter with 1-1/4 inch length of cut for standard-depth milling
• 4-flute, variable helix design reduces chatter and improves surface finish
• nACRo coating provides wear and oxidation resistance in high-temp cutting environments
• Centercutting geometry allows plunge and ramp entry cuts
• Submicron solid carbide grade for rigidity and edge retention
• h6 shank diameter tolerance for consistent tool holder fit and runout control

Compatibility

Designed for use with materials coded H, K, M, N, P, and S, covering high-temperature alloys, cast iron, stainless steel, non-ferrous metals, carbon and alloy steels, and titanium alloys. Fits standard 5/8 inch collets and end mill holders with h6 tolerance shanks.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and the tool holder is clean and free of chips before seating the tool. Confirm shank engagement depth meets the tool holder manufacturer's minimum recommendation. Follow machine tool manufacturer guidelines for runout inspection after tool installation.
