Our company independently developed and produced the HQ series diamond drill bits and reaming shells, which were deployed to project sites for practical drilling tests. The results demonstrated outstanding performance in drilling efficiency and wear resistance, perfectly adapting to on-site construction conditions. The measured outcomes were remarkable, earning full customer recognition and further enhancing our market reputation for superior practical performance.
