Shareate water well bit is designed and manufactured in accordance with the standards of the oil industry rotary bit. Combined with the leading mining rotary bit design and manufacturing technology, Shareate water well bit continues to deliver long life, high drilling efficiency and low drilling cost.
Shareate offers more than 30 kinds of water well bits with TCI (carbide buttons) and mill tooth configurations range from sizes 4 1/2 to 17 1/2 inches. Applications include rock formations from soft such as soft shale, clay and salt rock to medium-hard such as limestone, dolomite, sandstone and chert. We developed several series of bearings such as O-shaped rubber seals, flat rubber seals, and metal seals, which are suitable for different drilling processes such as conventional drilling, directional drilling, high temperature geothermal well drilling and high-speed rotary drilling.
Customization on Shareate water well bit is available for specific geology. Backed up by the global network and expert support, Shareate is continuously improving our services and solutions.
