ZRQ165-DHD350 drill bit features

ZRQ165-DHD350 drill bit is a kind of general purpose drill bit developed by our company according to the characteristics of domestic rock formations. Its side teeth are mining

Using eight 18mm alloys to ensure the wear resistance and fracture resistance of the alloy, and the large head adopts a concave layout.

The straightness of the drill bit during the drilling process is effectively ensured, and the bit body adopts a special heat treatment process, which effectively reduces the amount

Its breakage, collapse and other damage probability make the drill bit body and alloy life matched effectively, reflecting the high lifespan

The characteristics of life and high efficiency.
