Currently, its core product offerings span seven major series:

ZT

ZT Series Horizontal Directional Drills

With models ranging from 6 to 1,200 tons-covering the smallest to the largest units in the industry-these machines are designed for diverse ground conditions, including soil, sand, and soft rock. They serve as the primary equipment for trenchless construction projects involving municipal, oil and gas, and telecommunications pipelines.

AT

AT Series All-Terrain Rock HDD Rigs

Covering a tonnage range from 20 to 150 tons and capable of operating in all types of geological formations, this series represents the earliest-developed and most comprehensive lineup of rock-drilling horizontal directional drills (HDD) in China, specifically engineered for projects in hard rock formations with compressive strengths exceeding 80 MPa.

ZTSPZ

ZTSPZ Series Horizontal Auger Drilling Rigs

With a tonnage range spanning 110 to 300 tons, this series represents the most extensively developed product line of its kind among leading industry players. It is ideally suited for projects requiring zero-settlement conditions and for the high-precision drilling of pilot holes for pipe-roof support systems in tunneling-a solution that has gained significant popularity in overseas markets.

ZTTG

ZTTG Series Trenchless Pipe-Pushing Machines

With a capacity range of 300 to 750 tons, these machines are designed for large-scale trenchless engineering projects-such as providing auxiliary pushing force for pipeline installation (oil, gas, etc.)-as well as for emergency rescue operations.

ZTJN

ZTJN Series Tunneling/Boring Rigs

With a capacity range spanning from 6 to 80 tons, these rigs align with national "urban renewal" policies. They are extensively used for the renewal, repair, and replacement of urban pipelines, and have gained widespread recognition in Hong Kong and various Southeast Asian countries.

Drill Rods

Integrally Forged Drill Rods and Complementary Drilling Tools

Drillto is the only specialized manufacturer in China that produces both the primary drilling equipment and its corresponding drill rods. The company independently develops and manufactures a full range of supporting products-including integrally forged drill rods, reamers, and mud systems-ensuring superior compatibility with the primary drilling equipment.

In addition to hardware products, Drillto provides full-lifecycle technical services-including customized trenchless construction solutions, bespoke drilling rig development, and maintenance and technical support-thereby creating a complete, end-to-end loop that spans from equipment supply to on-site project execution.

 

Certificate

Customer Reviews

We have been using the ZT-42 drilling rig since 2022, and our experience has been very satisfactory. It offers high operational efficiency and sufficient torque. The rig is also equipped with a robotic arm, which eliminates the need for manual handling of drill rods-this significantly reduces labor requirements and boosts overall work efficiency. - A municipal engineering company in Changchun.

Mr. Ma

We have been using the ZT-280A drilling rig since 2024. It boasts high push-pull force and torque, making it exceptionally well-suited for large-diameter pipeline crossings. Its precise control and stable performance also make it ideal for long-distance drilling operations. Furthermore, the rig comes equipped with a high-capacity mud pump, which greatly facilitates operations in soil conditions that are not overly complex. - A trading company based in Ningbo.

Mr. Xu

 

The ZT-52 drilling rig features a compact design with a small footprint, making it exceptionally well-suited for urban construction projects. Since its delivery, we have found it very convenient to use-the diesel engine can be brought up to operating speed with the press of a single button. When encountering rock formations, the rig's dedicated 'rock mode' simplifies manual operation and significantly boosts rock-breaking efficiency-doubling our previous speed-while eliminating concerns about difficult hole-reaming or drill-string sticking. The entire process of adding or removing drill rods is managed via a single button, making the operation straightforward and easy to master, even for a novice operator. Furthermore, if the drill string encounters resistance and high torque during rotation, the power head spindle will automatically reverse upon the rig's rotation stopping. To prevent the resulting high-impact stress on the rotary motor, the rig is equipped with a protective circuit that effectively safeguards the motor. - A telecommunications engineering company based in Xinxiang.

Mr. Li

We have been using the ZT-100ATA drilling rig since 2024. It utilizes a dual-power-head mechanism-employing an outer pipe for directional control and an inner pipe for torque transmission-which ensures high precision during pilot hole drilling. The rig's mast can be adjusted for operation at angles ranging from 30° to 90° to accommodate various site conditions. Additionally, it is equipped with a multi-degree-of-freedom robotic arm capable of handling drill rods at different operating angles, which helps reduce manual labor costs. Powered by an electric motor, the rig delivers ample power while producing zero exhaust emissions, enabling eco-friendly construction and significantly lowering operational costs. - An energy technology company in Langfang.
