This type of spiral cutterhead is designed with a true shear cut. It requires less horsepower, makes smaller chips and less noise than any other type of of cutterheads do. If one knife edge is dull or damaged, just turn it to another edge in seconds and the cutterhead works pefectly as a new one again. This greatly reduces your down time. Replace the inserts only when four edges are dull. You don’t need to replace all the knives as you have to do with the conventional single straight knife. It pays you back in a very short time.
