1.The blade is designed with indexable hexagonal and double-sided, and has 12 cutting edges. 

2.Various forms, specifications, teeth number, diameter and other types of structural design, to provide customers with a variety of choices, dense tooth and ultra-dense tooth design, to achieve economic and efficient processing. 

3.Under the premise of ensuring the smooth chip removal, more core materials are retained, the rigidity and damping capacity of the blade are enhanced, the stable and reliable machining is realized, and the surface roughness of the blade is obtained by optimizing the design of the blade base and chip groove.
