Gws 120437 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The GWS 120437 is a 4-flute solid carbide square end mill designed for high-performance metal cutting across a range of workpiece materials. Built on the Series 1030 platform, it features a 0.5 inch mill diameter, a 0.625 inch length of cut, and a 2.5 inch overall length. The variable 38-degree helix angle and nACRo coating work together to reduce cutting forces, manage heat, and extend tool life in demanding applications. This end mill is a single-end, right-hand cut, right-hand flute tool with an upcut flute type and center-cutting capability. It is suited for use by machinists and tooling professionals in production and job-shop environments.

The GWS 120437 is rated for use with workpiece material categories H, K, M, N, P, and S, covering hardened materials, cast iron, stainless steel, non-ferrous metals, steel, and high-temperature alloys. The 0.5 inch square shank with h6 tolerance fits standard collet chucks and end mill holders. At a standard length classification, it is appropriate for general-purpose milling operations including slotting, profiling, and peripheral cutting where a short-to-medium reach tool is required. It is not an extended-reach configuration.

Key Features

• Submicron solid carbide grade for rigidity and wear resistance
• Variable helix design reduces chatter and harmonics during cutting
• nACRo coating provides thermal protection and extended tool life on difficult materials
• Center-cutting geometry allows plunge entry
• Right-hand cut and right-hand flute for standard milling setups
• h6 shank tolerance for precise fit in collet and end mill holder systems

Compatibility

Rated for workpiece material codes H, K, M, N, P, and S, covering hardened steels, cast iron, stainless steel, non-ferrous materials, carbon and alloy steels, and superalloys. Fits any standard 1/2 inch collet or end mill holder accepting an h6 tolerance shank.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Verify collet or holder cleanliness and proper torque per the machine tool manufacturer specifications before cutting. Do not exceed the tool's rated depth of cut or feed rate for the selected workpiece material.
