Product Description

Due to the existence of porous structure of powder metallurgy, the hardness value of powder metallurgy fluctuates in a small area, even if the measured macroscopic hardness is HRC20-35, the hardness of the particles after forming the parts will be as high as HRC60. These particles will cause the tool edge The mouth wears sharply. For powder metallurgy, Halnn Tools provides BN-K50, BNK30, BN-K10, BN-H21 brand PCBN inserts for customers to choose, the specific structure is as follows
