Gws 101068 Square End Mill 0.25 in 3 Flute Solid Carbide

Product Description

The GWS 101068 is a solid carbide square end mill from the Alumigator 1026 series, designed for high-performance milling of aluminum and non-ferrous materials. It features a 0.25-inch mill diameter, a 3-flute geometry, and a 37-degree helix angle that promotes efficient chip evacuation and reduces heat buildup during aggressive cuts. The extended reach design, with a 1.125-inch reach length, allows access to deeper features without sacrificing rigidity. The bright, uncoated finish on a submicron carbide substrate makes it well suited for aluminum applications where coatings can cause material adhesion. This tool is installed by machinists and CNC operators in production and job-shop environments.

The 101068 is built for milling aluminum, soft metals, and non-ferrous materials on CNC machining centers and manual knee mills. The right-hand cutting and right-hand flute direction are standard for conventional setups. The centercutting capability allows both plunge and peripheral cutting operations. The 0.375-inch length of cut and 2.5-inch overall length make it practical for shallow-to-moderate depth-of-cut applications in aluminum plate, extrusion, and cast stock.

Key Features

• 3-flute, 37-degree helix geometry optimized for aluminum chip evacuation
• Submicron solid carbide substrate for extended tool life
• Extended reach design with 1.125-inch reach length for deeper feature access
• Centercutting capability allows plunge milling and ramping operations
• Right-hand cut, right-hand flute, upcut flute type for standard CNC setups
• Bright uncoated finish reduces aluminum adhesion and built-up edge

Compatibility

Designed for use in standard 0.25-inch collets, ER collet chucks, and end mill holders on CNC machining centers and manual mills. Part of the GWS Alumigator 1026 series, intended for aluminum and non-ferrous milling applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the collet or tool holder is clean and free of debris before seating the shank. Follow machine tool manufacturer recommendations for runout tolerances and pull-out force when setting tool length. Verify spindle direction and programmed feed and speed parameters before engaging the cut.
