This is arguably the most important feature to consider when choosing an end mill for CNC machined aluminum. Again, aluminum is gummy and soft, which means it tends to stick in the flutes of your CNC mill. While coatings can help alleviate this issue, if you're using a 4- or 5-flute end mill to cut aluminum, even the best coatings may not help.

1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.
