Gws 310388 Square End Mill 5/8 Inch 4 Flute Solid Carbide

Product Description

The GWS 310388 is a solid carbide square end mill designed for precision milling across a wide range of workpiece materials. It features a 5/8 inch cutting diameter, a 1-5/8 inch length of cut, and a 3-1/2 inch overall length. The AlCrO-MAX coating provides thermal and oxidation resistance, extending tool life in demanding cutting conditions. With a 38-degree helix angle and upcut flute geometry, this end mill promotes efficient chip evacuation and clean surface finishes. It is centercutting, allowing direct plunge entry into the workpiece. Intended for use by machinists and tooling professionals in CNC and manual milling applications.

The 310388 is suited for milling operations on a broad material spectrum, including hardened steels, cast iron, stainless steels, non-ferrous metals, aluminum alloys, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. The standard length configuration and 5/8 inch square shank with h6 tolerance make it compatible with standard collet and end mill holder setups. This tool is appropriate for both roughing and finishing passes in production and job shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlCrO-MAX coating for high-temperature and oxidation resistance
• 38-degree helix angle with upcut flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge milling
• Right-hand cut and right-hand flute, standard CNC orientation
• h6 shank tolerance for precise tool holder fitment

Compatibility

Designed for use in standard 5/8 inch collets and end mill holders. Suitable for machining hardened steels, cast iron, stainless steels, non-ferrous metals, aluminum, and superalloys per Series 2100 application guidelines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning the cut to confirm proper seating and minimize tool deflection.
