Gws 120668 Square End Mill 3/4 Inch 3 Flute Carbide

Product Description

The GWS 120668 is a solid carbide square end mill designed for precision milling operations in metal fabrication, tool and die, and general machining environments. Built to Series 1015 standards, this single-end tool features a 0.75 inch mill diameter, a 1.625 inch length of cut, and a 4 inch overall length. The submicron carbide grade provides rigidity and edge retention in demanding cutting applications. The bright uncoated finish makes it well suited for non-ferrous metals and applications where coating interaction is a concern. Installation and use are performed by machinists and CNC operators in shop environments.

This end mill is appropriate for peripheral and slot milling in both manual and CNC machining centers. The 3-flute geometry balances chip evacuation and cutting efficiency, making it a practical choice for moderate to aggressive material removal in aluminum, brass, plastics, and similar materials. The right-hand cut and right-hand upcut flute configuration is standard for conventional milling setups. Note that this tool is not centercutting and is not suited for direct plunge entry.

Key Features

• Submicron solid carbide construction for improved hardness and edge retention
• 3-flute upcut geometry promotes effective chip evacuation during milling
• 37-degree helix angle reduces cutting forces and supports smooth surface finishes
• Chipbreaker geometry assists with chip control in longer cuts
• Bright uncoated finish compatible with non-ferrous metals and plastics
• h6 shank diameter tolerance ensures accurate tool holder fitment

Compatibility

Designed as a standard OEM-style solid carbide square end mill for use in tool holders accepting a 0.75 inch square shank, compatible with conventional and CNC milling machines configured for right-hand cut tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the tool holder to the minimum clamping depth recommended by the holder manufacturer before engaging the spindle. Verify spindle direction is set to right-hand rotation prior to operation. Because this tool is not centercutting, avoid direct axial plunge cuts; use ramping or helical entry strategies instead.
