Gws 120665 Square End Mill 5/8 in 3 Flute Solid Carbide

Product Description

The GWS 120665 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. It features a 5/8 inch cutting diameter with a 1-5/8 inch length of cut, a 3-1/2 inch overall length, and a 5/8 inch square shank. The three-flute, right-hand cutting geometry with a 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright uncoated finish suits general-purpose use across a range of ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC programmers working in job shops and production environments.

This end mill is suited for slotting, profiling, and peripheral milling in vertical and horizontal machining centers as well as manual knee mills. The single-end configuration and standard length make it a practical choice for conventional roughing and finishing passes. Its centercutting capability allows plunge entry directly into the workpiece without a pre-drilled hole. The upcut flute direction pulls chips upward and away from the cut zone, which is especially useful when working with aluminum, mild steel, and similar materials.

Key Features

• 5/8 inch cutting diameter with 1-5/8 inch length of cut for controlled material removal depth
• Solid carbide construction using submicron carbide grade for wear resistance and rigidity
• Three right-hand flutes with 37-degree helix angle for efficient chip flow
• Centercutting design allows direct plunge milling without pre-drilling
• Bright uncoated finish for compatibility with a broad range of workpiece materials
• Square shank and standard length for straightforward collet or end mill holder fitment

Compatibility

Designed as an OEM-style solid carbide square end mill suitable for use in standard 5/8 inch collets, end mill holders, or hydraulic chucks on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes must be performed with the machine fully powered down and the spindle at a complete stop. A licensed machinist or qualified CNC operator should verify runout after seating the tool in the holder before beginning a cut. Follow the tool manufacturer and machine tool OEM guidelines for proper clamping torque on collet nuts and end mill holders. Inspect the cutting edges for chipping or wear before each use and replace the tool if damage is present.
