Our 1/4" Square End Mill is perfect for general purpose machining of aluminum and other non-ferrous metals, as well as a variety of other materials.

All of our End Mills feature a 45° helix for superior chip evacuation, along with the latest generation Zirconium Nitride (ZrN) coating for exceptional tool-life and performance.

ZrN was developed specifically for machining aluminum, yet it is excellent for machining all non-ferrous materials and is highly recommended for machining fiberglass, nylon, and most polymer materials.

This tool is also available in our CNC Aluminum Cutting End Mill Set, a versatile set of high quality, long lasting, solid carbide end mills for the most common CNC projects that require cutting aluminum, or a variety of other materials.
