Water Well Bits

Water well bits are mainly used in the drilling of water wells, geothermal wells, coalbed methane resources and other drilling projects.

PRODUCT OVERVIEW

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.

MAIN FEATURES

Unique bearing design makes the structure more stable, superior in
performance and strong in adaptability.
Adopt high temperature resistant and wear resistant rubber sealing
structure to prolong service life.
Precisely designed cutting structure is suitable for formations of
different hardness and lithology.
Excellent oil storage system balances the pressure difference between
the inside and outside of the bearing, extending the life and stability of
drill bit.
Diverse bit strengthening features can solve different types of
problems in dilling
process.

BRAND INTRODUCTION

"echoes the meaning of "Tornado", Highlighting not only the flexible Characteristics of a Tornado™but also the powerful hurricane-like energy contained in a drill bit for the application of drilling rocks ,crushing stones or taking water for prospecting.

Tornado water well bits can provide different steel types, bearing types, sealing types, cutting structure types, lug back protection structures according to customer needs, and has many additional features to choose from. With the flexible product characteristics, plus Shareate’s strong technical support of design, manufacturing and services, we can tailor our products according to customers’ needs, and provide customers with the most suitable water well bits.

Tornado’s product type

Mill tooth(MT) tricone bit: it is suitable for very soft formation with high drilling efficiency and excellent diameter protection ability. According to different formation hardness and drillability, the mill tooth bit can be machined with different height and width teeth on the outer line of the cone, and weld a layer of WC wear-resistant material on the surface of the teeth to enhance wear resistance.

Tungsten carbide insert (TCI) bit: It has strong adaptability and is suitable for medium soft formation to hard formation, high rock breaking efficiency and strong diameter keeping ability. TCI bits use carbide teeth of different heights, shapes and materials to deal with formations of varying hardness and rock properties.
