wire-Line Diamond Impregnated Bit

Wireline double tube bits are the most common design of bits used in exploration today.

Product Description

Wireline double tube bits are the most common design of bits used in exploration today. This drilling system allows the core to be retrieved with a wireline without having to pull rods. With extensive experience of what is really required in the field, and unique expertise in metallurgy, we have brought an international team of drillers, engineers and metallurgists together to produce our best bit yet. The operating range of each diamond bit has been substantially increased providing exceptional productivity with oustanding bit life.
