Gws 310403 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The GWS 310403 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built from submicron-grade carbide and coated with AlCrO-MAX, this tool delivers extended tool life and heat resistance in ferrous and hardened materials. It features a 5/8 inch cutting diameter, a 2-1/8 inch length of cut, and a 4-inch overall length. With 4 flutes and a 38-degree helix angle, it provides efficient chip evacuation and a smooth cutting action suitable for slotting, profiling, and peripheral milling operations. This end mill is installed by machinists and tooling technicians in CNC and manual milling setups.

The GWS 310403 is suited for use in production and job-shop environments where consistent tool performance is required across a range of materials including steel, stainless steel, and cast iron. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. The upcut flute geometry promotes chip removal from the cut zone. It is part of the GWS Series 2100 line and is a single-end, standard-length tool appropriate for typical milling depth requirements where extended reach is not needed.

Key Features

• Submicron solid carbide construction for rigidity and wear resistance
• AlCrO-MAX coating for elevated heat resistance and extended tool life in ferrous materials
• 38-degree helix angle with upcut right-hand flute direction for efficient chip evacuation
• 4-flute design balances material removal rate with surface finish quality
• Center-cutting geometry allows plunge entry into workpiece
• Square shank with 5/8 inch diameter for secure clamping in standard collet or end mill holders

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/8 inch collet chucks, end mill holders, and Weldon-style tool holders used in CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the holder and torque set screws or collet nuts to the tool holder specification before operation. Inspect the cutting edges for chips or wear before each use, and verify runout with a dial indicator when precision surface finish is required.
