The company I'm doing an internship with has had problems with drill bits cracking. They are made from 17-4 PH Condition H900 and are coated in TiN.
Apparently the process of coating the bits is affecting the hardness and shape of the bits.
I've contacted several vendors to see if the coating process is a plausible explanation for the hardness issues, and have gotten mixed responses.
Is it possible the process of the TiN coating is affecting the hardness of the bit in a negative way? If so why? Would using 455 SS H900 be a solution?
Thanks.
