Rotary Drill Bits

Drag Bits

Maxdrill has developed drag bits to drill pilot holes since they produce cuttings that are easy for logging. Maxdrill’s drag bits are recommended to apply in soft conformations, such as, sand, clays and soft stone. They are usually used in the fields of water well, mining, geothermal projects, environmental and site investigation.

We offer the step type and the chevron type of drag bits. Step type Chevron type Tricone Bits

Maxdrill’s long-term efforts in development and innovation bring about an exceptional upgrade of tricone bits. Maxdrill’s tricone bits, designed with the optimal bearing structure and equipped with tungsten carbide inserts, incredibly perform well when it comes to extremely hard rocks. Maxdrill’s standardized production and quality control ensure safety of use, high drilling efficiency and high rate of penetration.

Tricone bits are widely used in well drilling, featuring:
Optimal inserts
Maxdrill designs tungsten carbide inserts in different shapes and grades particularly for formations that have different features, such as, hardness and composition, to serve projects involving complex formations.
Enhanced gauge and shirttail protection
Applying the “step” design, Maxdrill has developed tricone bits that feature quick water draining and debris cleaning, which reduces abrasion on a gauge and a shirttail and thus improves service life.
