Gws 315669 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The GWS 315669 is a solid carbide square end mill designed for precision milling in metal, composites, and hard materials. It features a 3/4 inch diameter with a 1 inch length of cut and a 3-flute geometry that balances chip evacuation with surface finish quality. The ZrN (zirconium nitride) coating reduces friction and improves tool life in ferrous and non-ferrous applications. At 6 inches overall length with an extended reach design, this single-end mill suits deep-pocket and extended-reach milling setups. It is installed and operated by machinists and tooling technicians on vertical and horizontal CNC milling machines.

This end mill is suited for production and job-shop milling operations requiring accurate square-shoulder cuts, slot milling, and peripheral milling. The 37-degree helix angle promotes smooth cutting action and efficient chip flow. The right-hand cut and right-hand flute direction make it compatible with standard CNC spindle configurations. The submicron carbide grade provides edge retention in demanding materials. Extended reach capability allows access to deep features where standard-length tooling cannot reach.

Key Features

• 3/4 inch cutting diameter with 1 inch length of cut for square-shoulder and slot milling
• 3-flute upcut design balances chip clearance and finish quality
• ZrN coating reduces tool wear and friction in ferrous and non-ferrous materials
• 37-degree helix angle for smooth cutting action and efficient chip evacuation
• Extended reach at 3-3/8 inch reach length for deep-feature access
• Submicron solid carbide grade for edge retention in hard or abrasive materials

Compatibility

Designed as a standard-shank solid carbide square end mill compatible with CNC milling machine tool holders accepting a 3/4 inch shank diameter, including ER collet chucks, end mill holders, and hydraulic chucks.

Installation Notes

Installation and tool changes must be performed by qualified machining personnel with the machine powered down and the spindle at a full stop before handling. Ensure the tool holder bore and shank are clean and free of chips or contamination before clamping. Follow machine tool manufacturer torque specifications for the tool holder type in use. Verify runout with a dial indicator after seating to confirm proper tool engagement before beginning a cut.
