Gws 100955 Square End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The GWS 100955 is a solid carbide square end mill designed for high-performance milling in aluminum and non-ferrous materials. It features a 1/4 inch cutting diameter, a 3/4 inch length of cut, and a 37-degree helix angle optimized for chip evacuation in softer metals. With three flutes and a right-hand cutting and flute direction, it delivers clean, efficient material removal. The submicron carbide grade provides edge retention and resistance to wear under demanding cutting conditions. This tool is installed by machinists and CNC operators in shop and production environments.

The GWS 100955 is well suited for face milling, slotting, and profiling operations on aluminum, brass, copper, and similar non-ferrous workpiece materials. Its bright/uncoated finish and upcut flute geometry make it particularly effective in applications where chip clearance is critical. The 2-1/2 inch overall length and 1/4 inch shank diameter fit standard collet chucks and toolholders used on vertical machining centers, CNC routers, and manual knee mills. It ships as a single-end tool with no extended reach configuration.

Key Features

• 1/4 inch cutting diameter with 3/4 inch length of cut for precise shallow-to-medium depth passes
• 37-degree helix angle promotes aggressive chip evacuation, reducing heat buildup in aluminum
• Three flutes with upcut geometry for clean finish on non-ferrous materials
• Submicron solid carbide construction for extended tool life and edge stability
• Center-cutting capable, allowing plunge entry into workpiece material
• Bright/uncoated finish suitable for use with aluminum-specific cutting fluids and lubricants

Compatibility

Designed for use with 1/4 inch collet chucks, ER-style toolholders, and end mill holders on CNC machining centers, CNC routers, and manual milling machines. Part of the GWS Series 1025 Alumigator line, intended for non-ferrous and aluminum milling applications.

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 loading or changing tooling. Confirm the shank is fully seated in the collet or toolholder and torqued to the toolholder manufacturer specifications before beginning any cutting operation. Verify runout with a dial indicator after seating to prevent premature tool wear or workpiece damage.
