Gws 313761 Square End Mill 1/8 in 2 Flute Solid Carbide

Product Description

The GWS 313761 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built with a 1/8 inch mill diameter and a 45-degree helix angle, this single-end tool delivers clean, aggressive cutting action in a compact form factor. The ZrN (zirconium nitride) coating improves surface hardness and heat resistance, extending tool life in abrasive materials. With 2 right-hand flutes and a right-hand cutting direction, it is suited for general-purpose profiling, slotting, and contouring cuts. This tool is installed by machinists and CNC operators working with precision spindle toolholding systems.

This end mill is suited for use in CNC machining centers and manual milling machines where small-diameter tooling is required. The extended reach design, with a reach length of 1-3/8 inches and an overall length of 3 inches, allows access to deeper features or recessed pockets without interference. The 1/4 inch length of cut and 1/8 inch shank diameter make it a practical choice for fine detail work, engraving paths, and tight-tolerance slot milling in ferrous and non-ferrous materials. The submicron carbide grade supports performance in harder workpiece materials.

Key Features

• 1/8 inch mill diameter with matching 1/8 inch shank for direct collet mounting
• ZrN coating for improved wear resistance and heat dissipation
• 45-degree helix angle for efficient chip evacuation and smooth cutting action
• Extended reach design with 1-3/8 inch reach length for deep-feature access
• Center-cutting capable, allowing plunge entry into workpiece material
• Submicron solid carbide grade for rigidity and edge retention

Compatibility

Designed as an OEM-style replacement or direct-use tooling for CNC milling machines and machining centers accepting 1/8 inch shank collets or toolholders. Part of GWS Series 2012.

Installation Notes

This end mill is installed by machinists using a collet chuck or end mill holder rated for the 1/8 inch shank diameter. Ensure the spindle and toolholder are clean and free of debris before seating the shank. Follow machine manufacturer torque specifications for collet nut tightening. Verify runout with a dial indicator before beginning production cuts to protect the tool and workpiece.
