These coated flat endmills are perfect for cutting aluminum. They have a specialty coating which provides a better finish, longer lifespan, and a superior cut compared to a non-coated endmill.
ZrN also works well for machining Titanium and Aluminum Alloys, Nickel, Brass, Copper, Cast Iron and Zinc.
Note: if you've got a Nomad, you'll also need a .25" collet. If you've got a Shapeoko, these are great cutters for the DeWalt trim router
You'll get a pack of two (2) of these cutters.
