When drilling metal, the condition and wear of a drill bit directly affect hole accuracy, surface finish, and overall machining efficiency. Many engineers overlook the gradual degradation of drill bit performance during production, only realizing the problem when hole diameters go out of tolerance, cutting temperatures rise, or machine loads increase abnormally. Promptly identifying the […]

In production line machining, selecting and procuring the right U drill bit size is critical for ensuring holemaking efficiency and precision. Different machine types, material properties, and drilling depths directly impact tool size and structure compatibility. Improper selection can lead to hole diameter errors, chip accumulation, premature tool wear, and increased tool replacement frequency, which
