Gws 315025 Square End Mill 3/4 in 3 Flute Solid Carbide Zrn

Product Description

The GWS 315025 is a solid carbide square end mill designed for high-performance material removal in CNC milling operations. With a 3/4 inch cutting diameter, 3 flutes, and a 37-degree helix angle, it delivers efficient chip evacuation and smooth cutting action across a wide range of workpiece materials. The ZrN (Zirconium Nitride) coating adds surface hardness and reduces friction at the cutting edge, extending tool life in production environments. Manufactured from submicron-grade carbide, this end mill is built for precision work where dimensional accuracy and edge retention matter. It is suitable for machinists, tool-and-die shops, and production CNC operations.

The 315025 is configured for right-hand cutting and right-hand flute direction with an upcut flute geometry. The 3 inch length of cut accommodates deeper pocket and slot milling applications, while the 6 inch overall length provides extended reach into workpiece features without requiring a separate extended-reach toolholder. The 3/4 inch shank diameter is a standard size compatible with common ER collets, end mill holders, and Weldon-style tool holders used in vertical and horizontal machining centers.

Key Features

• 3/4 inch cutting diameter with 3/4 inch shank for direct holder compatibility
• 3 flutes with 37-degree helix angle for efficient chip flow and reduced cutting forces
• ZrN coating for improved wear resistance and lower friction at the cutting edge
• Submicron-grade solid carbide construction for rigidity and edge retention
• Centercutting geometry allows plunge entry into the workpiece
• 6 inch overall length with 3 inch length of cut for deep-feature access

Compatibility

Designed for use in standard CNC machining centers and manual mills equipped with 3/4 inch toolholders including ER collet chucks, end mill holders, and Weldon-flat holders. Right-hand spindle rotation required.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the recommended minimum insertion depth per the toolholder manufacturer's specification to prevent pullout under load. Do not exceed the tool's rated depth of cut or feed rate for the material being machined.
