4 flute end mills are end mills that have 4 cutting edges and are used for all end mill operations. The flute volume is less on 4 flute mills, but they are the most common number of flutes. The larger number of flutes allows for a faster feed rate than 2 or 3 flute end mills. They perform well in most materials, but they are not generally used for milling aluminum.
