Gws 100964 Square End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The GWS 100964 is a single-end square end mill designed for high-performance milling in aluminum and non-ferrous materials. Built from submicron-grade solid carbide, it provides the rigidity and edge retention needed for demanding cutting operations. The 3/8 inch diameter cutting head features three flutes with a 37-degree right-hand helix, promoting efficient chip evacuation and reduced heat buildup at the cutting zone. With an overall length of 2.5 inches and a 1 inch length of cut, this tool balances reach and stability. It ships bright and uncoated, making it ready for immediate use. Licensed machinists, tool-and-die shops, and CNC operators typically run this tool in production and prototype environments.

This end mill is engineered for aluminum milling applications where chip load management and surface finish are critical. The 37-degree helix angle and upcut flute direction work together to pull chips away from the workpiece, reducing re-cutting and built-up edge. The centercutting geometry also allows plunge entry, giving the operator flexibility in toolpaths. It is equally suited to conventional milling machines and modern CNC machining centers handling aluminum extrusions, plate, and cast stock.

Key Features

• Submicron-grade solid carbide construction for hardness and wear resistance
• 3 flutes with 37-degree right-hand helix for aggressive chip evacuation in aluminum
• Centercutting capable, supporting plunge and ramp entry operations
• Upcut flute direction reduces chip re-cutting and surface damage
• Bright/uncoated finish optimized for aluminum and non-ferrous alloys
• Series 1025 Alumigator geometry purpose-built for aluminum milling

Compatibility

Designed as an OEM-style replacement and standard tooling option for 3/8 inch collet or end mill holders on vertical machining centers, knee mills, and CNC routers capable of running solid carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully in a properly sized collet or end mill holder and torque the retention mechanism per the machine tool manufacturer specification. Inspect the tool for chips or cracks before each use. Verify spindle speed and feed rate settings are appropriate for the workpiece material before engaging the cut.
