Gws 315192 Square End Mill 3/4 in 3 Flute Solid Carbide Zrn

Product Description

The GWS 315192 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. Built from submicron carbide and coated with zirconium nitride (ZrN), this tool delivers hardness and wear resistance suited to demanding cut cycles. The 3/4 inch diameter cutter features 3 flutes with a 37-degree right-hand helix, a 1-5/8 inch length of cut, and a 4 inch overall length. The center-cutting geometry allows direct plunging into workpieces. This tool is installed and used by machinists and CNC operators working in job shops, production facilities, and toolroom environments.

This end mill is suited for slotting, profiling, and peripheral milling in a range of workpiece materials. The ZrN coating reduces friction and extends tool life compared to uncoated carbide, making it a practical choice for medium-to-high production runs. The 3/4 inch shank diameter matches the cutter diameter for direct chuck or collet holding without a reduction bushing. It is a single-end tool in the GWS Series 2031 lineup.

Key Features

• 3/4 inch mill diameter with matching 3/4 inch shank diameter for direct collet holding
• Submicron solid carbide construction for rigidity and edge retention
• ZrN (zirconium nitride) coating for reduced friction and extended tool life
• 3 flutes with a 37-degree right-hand helix and upcut flute geometry
• Center-cutting design allows direct plunge entry into workpieces
• 1-5/8 inch length of cut with 4 inch overall length

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting 3/4 inch straight-shank end mills via ER collets, end mill holders, or side-lock holders.

Installation Notes

Installation is performed by a machinist or CNC operator. Power down and lock out the spindle before changing tooling. Seat the shank fully in the collet or holder to the minimum insertion depth required for your toolholder specification, and torque the clamping mechanism per the toolholder manufacturer guidelines. Inspect the cutting edges and coating before each use and replace the tool at first signs of chipping or excessive wear to avoid workpiece damage.
