New proposal for direct cutting of hardened steels

4-flute ball end mill enables high-cutting-depth high-feed-rate cutting of hardened steels.
Provides more than 4 times the cutting efficiency of conventional 2-flute ball end mills.
In addition, use of new cutting methods combining helical cutting (oblique cutting) and
trochoidal cutting (side surface cutting) achieves greatly reduced cutting times.
