Gws 120432 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The GWS 120432 is a solid carbide square end mill designed for precision metal removal across a wide range of workpiece materials. It features a 1/8 inch cutting diameter, a 1/4 inch length of cut, and a 1-1/2 inch overall length with a 1/8 inch shank diameter. The 4-flute, variable helix geometry reduces chatter and improves chip evacuation, while the nACRo finish provides enhanced wear resistance and thermal stability at the cutting edge. The chipbreaker design further aids chip control during continuous cuts. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.

This end mill is suited for milling operations on materials including high-temp alloys, cast iron, stainless steel, non-ferrous metals, carbon steel, and titanium, corresponding to material codes H, K, M, N, P, and S. The upcut flute geometry pulls chips away from the workpiece surface, making it well-suited for slotting, profiling, and finish passes in shallow-depth applications. The centercutting configuration allows direct plunge entry without a pre-drilled hole. Standard length classification and h6 shank tolerance ensure reliable tool holding in collet or shrink-fit systems.

Key Features

• Variable helix design reduces harmonic vibration and chatter during aggressive cuts
• nACRo coating provides heat and wear resistance for extended tool life on hard and abrasive materials
• Chipbreaker geometry improves chip segmentation and evacuation in slotting operations
• Centercutting capability allows direct plunge milling without pilot drilling
• Upcut right-hand flute direction pulls chips clear of the cut zone
• h6 shank tolerance ensures precise fit in collet and shrink-fit toolholders

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 1/8 inch straight shank with h6 tolerance.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Secure the shank fully within the toolholder to the recommended gauge line before tightening. Verify spindle speed and feed rate settings are appropriate for the workpiece material and cutting depth before engaging the cut. Inspect the cutting edge for wear or chipping before each use and replace the tool if edge integrity is compromised.
