ZRQ225-DHD380 drill bit features

ZRQ225-DHD380 drill bit is a universal drill bit developed by our company according to the characteristics of domestic rock formations, and its side teeth are adopted

10 18mm alloys ensure the wear resistance and fracture resistance of the alloy. At the same time, the large head adopts a concave layout.

Effectively ensures the straightness of the drill bit during the drilling process, and the drill body adopts a special heat treatment process, which effectively reduces its

The probability of damage such as fracture and block collapse effectively matches the life of the bit body and the alloy, reflecting the high lifespan

And the characteristics of high efficiency.
