Gws 100994 Square End Mill 0.25 in 3 Flute Solid Carbide

Product Description

The GWS 100994 is a solid carbide square end mill engineered for precision milling in demanding applications. With a 0.25 inch mill diameter, a 1.125 inch length of cut, and a 3-flute geometry, this tool delivers clean, accurate results in materials that demand tight tolerances. The 37-degree helix angle promotes efficient chip evacuation and reduces cutting forces. It ships with a bright, uncoated finish and is built from submicron carbide grade material, giving it excellent wear resistance and edge retention. Licensed machinists, CNC operators, and tool-and-die professionals will find this end mill a reliable fit for high-speed aluminum and non-ferrous milling operations.

This end mill belongs to the GWS 1025 Alumigator series, which is optimized for aluminum and soft non-ferrous alloys. Its right-hand cutting and right-hand flute direction make it compatible with standard vertical and horizontal milling centers. The single-end, centercutting configuration allows plunging as well as peripheral cutting, giving the operator flexibility in slot milling, profiling, and pocket work. It is equally suited to production-floor CNC machining and toolroom use.

Key Features

• 0.25 inch mill diameter with 0.25 inch shank diameter for direct collet or end mill holder fitment
• 1.125 inch length of cut supports deeper slot and pocket passes in a single setup
• 3-flute design balances chip clearance with surface finish in aluminum and non-ferrous materials
• 37-degree helix angle promotes aggressive chip evacuation and reduced heat buildup
• Submicron solid carbide construction provides superior hardness and edge retention over standard micrograin grades
• Bright, uncoated finish - no coating buildup that could affect dimensional tolerances on close-tolerance cuts

Compatibility

Part of the GWS 1025 Alumigator series, designed as an OEM-style replacement or direct-use end mill for CNC milling machines and manual mills accepting a 0.25 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production run. Always spin down the spindle and confirm zero RPM before changing tooling.
