Explore our high-performance fleet of rotary drilling setups, soil-mixing equipment, and premium core drilling accessories engineered for optimal penetration rates and long-term durability in challenging geologies.
In modern geotechnical exploration and resource extraction, the integrity of the drill string is paramount. Core drilling rods, tools, and diamond bits operate under extreme torsional, tensile, and compressive stresses. Choosing high-specification drilling components directly determines the success, speed, and safety of deep-hole projects.
Rapid urbanization, underground transit expansions, and deep mineral exploration require standardized wireline core drilling systems (NQ, HQ, PQ, and SQ). Reliable tools prevent downhole failures that risk expensive operational delays.
Modern drilling rods employ high-grade alloy steels (such as 42CrMo or equivalent Geotech grades) treated with precision friction welding and induction-hardened thread ends to increase fatigue life and resist thread stripping.
Matrix design dictates penetrative efficiency. From impregnated diamond bits targeting extremely hard, massive formations (granite, basalt) to surface-set diamond bits for softer, abrasive formations (sandstone, limestone), engineering the right crown profile optimizes fluid hydraulics and operational lifetime.
| System Designation | Hole Diameter (mm) | Core Diameter (mm) | Typical Formation Compatibility |
|---|---|---|---|
| AQ / AQTK | 48.0 mm | 27.0 mm / 35.5 mm | Hard, solid formations; shallow to medium depth drilling. |
| BQ | 60.0 mm | 36.4 mm | Medium to hard massive rock; standard core recovery. |
| NQ / NQ2 / NQ3 | 75.7 mm | 47.6 mm / 50.7 mm / 45.0 mm | Highly fractured or unstable geologies; mineral exploration baseline. |
| HQ / HQ3 | 96.0 mm | 63.5 mm / 61.1 mm | Soft to medium-hard rock; geotechnical soil-rock boundary testing. |
| PQ / PQ3 | 122.6 mm | 85.0 mm / 83.0 mm | Unconsolidated formations; large core samples for structural evaluation. |
China's geotechnical manufacturing sector leverages integrated raw steel supply chains, automated CNC machining clusters, and specialized thermal treatment processes to produce tools that meet stringent international standards (including API and ISO specifications) at a lower total cost of ownership.
SINOVO Group's main factory, located in the Xianghe Emerging Industry Demonstration Zone (covering 67 mu, representing a 120 million RMB investment), is situated 100 kilometers from the Port of Tianjin. This strategic placement ensures streamlined global logistics and minimizes inland transit costs, allowing us to pass the savings directly to international procurement teams.

SINOVO Group is a professional supplier of construction machinery and deep exploration solutions. Our team has worked in foundation engineering and geological exploration since the early 1990s. Over decades of innovation, we have built alliances with top global component suppliers and built local service centers in hubs like Singapore, Dubai, and Algiers.
Our products carry ISO9001:2015, CE, and GOST-TR certifications. In Southeast Asia, our piling machinery is recognized for its reliability. In Africa, we are an established supplier of heavy exploratory equipment, backed by responsive technical support and a ready stock of spare parts.
Downhole tooling must withstand extreme wear, abrasion, and high torque. Here is how SINOVO optimizes the metallurgical design of core drill rods and bits to ensure performance in demanding conditions:
We use cold-drawn seamless tubing made from premium alloys like 45Mn2 or 30CrMnSiA. This guarantees high tensile strength, precise straightness, and uniform wall thickness, minimizing runout in deep holes.
By friction-welding tool joints to the rod body, we create a strong, clean bond. Post-weld heat treatment relieves internal stresses, preventing breakages at the joint interfaces under high torque.
Our CNC machinery cuts precise, standardized threads (including Q-series and metric configurations). We apply liquid nitriding or surface hardening to protect the threads, ensuring reliable makeup and breakout cycles.
Our core team members began serving the domestic Chinese construction machinery industry, building expertise in drilling mechanics and hydraulic systems.
We established TEG Far East Company in Singapore. This strategic hub coordinates sales, parts distribution, and technical service across Southeast Asia.
We invested 120 million yuan in our 67-mu manufacturing base in the Hebei Xianghe Demonstration Zone, centralizing R&D for geological and piling equipment near major ports.
Our equipment operates in more than 120 countries. We continuously update our ISO9001 and CE certified designs to improve reliability for our global customers.
To ensure smooth operation on the job site, we back our core drill rods, casing pipes, and drilling rigs with a comprehensive technical support program:
Our design centers bring together hydraulic engineers, metallurgical experts, and drilling field consultants. With over 30 years of history, we focus on technical development, securing multiple national patents for torque transmission, rock crushing, and pile breaking systems.
Our manufacturing processes follow international standards to ensure reliability, safety, and consistent performance across all models.
From large bridge piling in Southeast Asia to mineral exploration in Africa, SINOVO tools and rigs are chosen for their reliability in challenging geological conditions.
