For milling most types of non-ferrous metals and non-metals, especially the free cutting, very ductile aluminum and zincs. Radial edged. Two large flutes for easy chip removal. Use when mahcine horsepower is too low for high chip capacity end mills. Compare price to solid carbide of the same diameter. Carbide is expensive and only used on the cutting edges.
