Gws 100997 Square End Mill 5/16 in 3 Flute Solid Carbide

Product Description

The GWS 100997 is a solid carbide square end mill designed for high-performance material removal in precision machining applications. With a 5/16 inch cutting diameter and a 1-1/8 inch length of cut, this tool is built for shops that demand accuracy and tool life. The 3-flute geometry and 37-degree helix angle promote efficient chip evacuation and smooth cutting action, particularly in aluminum and non-ferrous materials. Manufactured from submicron carbide grade stock, the 100997 delivers the edge retention and rigidity needed for demanding milling operations. It ships in a bright, uncoated finish.

This end mill is best suited for CNC milling operations on aluminum, plastics, and softer non-ferrous metals where chip clearing and surface finish are priorities. The Alumigator Series designation reflects its geometry optimization for aluminum milling, where the 37-degree right-hand helix pulls chips upward and away from the cut. Machinists and CNC operators in job shops, aerospace fabrication environments, and production facilities will find this tool appropriate for slotting, profiling, and pocket milling at standard cutting depths.

Key Features

• 5/16 inch cutting diameter with matching 5/16 inch shank diameter for direct collet clamping
• 1-1/8 inch length of cut suitable for moderate-depth slotting and profiling
• 3-flute design with 37-degree right-hand helix for efficient chip evacuation in aluminum
• Submicron solid carbide construction for superior hardness and edge retention
• Center-cutting capable - allows plunge entry without pre-drilling
• Bright uncoated finish; 3 inches overall length; single end configuration

Compatibility

Designed as an OEM-style replacement or standard tooling option within the GWS 1025 Alumigator Series, compatible with any CNC or manual milling machine using a standard 5/16 inch collet or end mill holder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing tooling. Seat the shank fully in the collet or end mill holder and torque the retention hardware to the machine manufacturer's specification using the appropriate wrench. Do not exceed the recommended axial depth of cut for the tool diameter, and verify runout with a dial indicator before beginning production cuts.
