Machining aluminum? This Titan end mill is built for the job! It's a 1/4-inch diameter, 2-flute, solid carbide tool with a 45-degree high helix. That geometry helps shearing aluminum efficiently and clears chips fast. The Zirconium Nitride (ZRN) coating is a game-changer for aluminum – it resists built-up edge and allows for higher speeds/feeds and longer tool life compared to uncoated or TiN tools. It has a 0.020-inch corner radius for a bit more edge strength and a smoother finish, and it's center-cutting so you can plunge and slot. With a 1-1/4 inch length of cut and 3-inch overall length, it's a long-reach style for deeper pockets. Made in the USA from premium sub-micrograin carbide. Perfect for CNC routers, mills, or any shop looking for a high-performance aluminum cutter.
