All the bits are optimized in designing and manufacturing by using CAD/CAM technology, and are made of superior cutting elements and corrosion resistant matrix with long service life. There are 3 kinds of crown profiles: parabolic, round and cone 3/8", 1/2", 3/4", and 1" PDC cutters are at customers' option.
