Explore our primary machinery catalog, manufactured with world-class hydraulics, rugged steel configurations, and engineered specifically for challenging geologies.
Modern civil infrastructure projects require foundations to penetrate deeper into high-strength bedrock, such as granite, basalt, and heavily cemented sandstone. Traditional flat augers often fail to discharge high-density rock chips efficiently, leading to rotational friction loss and severe thermal wear on the kelly bar connection. The industry is rapidly shifting toward progressive pitch rock augers. By varying the flight pitch from tight configurations at the cutter head to wider pitches at the top, designers allow excavated cuttings to expand, minimizing structural jam-ups and maximizing drilling torque efficiency.
Furthermore, advancements in tungsten carbide metallurgy have paved the way for self-sharpening bullet teeth. Premium manufacturers are now integrating chromium-carbide hardfacing overlays directly onto the auger flights, extending flight lifespan by up to 300% in highly abrasive conditions.
Procurement teams for Tier-1 engineering firms evaluate drilling tools based on Total Cost of Ownership (TCO) rather than initial acquisition cost. Key purchase decision indicators include:
SINOVO Group's production base leverages advanced automated manufacturing systems to assure consistent quality and pricing control. Located in Hebei Xianghe Emerging Industry Demonstration Zone, our facility is optimized for rapid transit, sitting just 100 kilometers from the Tianjin port, significantly reducing trans-oceanic logistics costs.
By using robotic welding arms for tooth-pocket placement, SINOVO ensures that the drilling angles of every carbide bullet cutter are mathematically aligned. This precise alignment mitigates uneven loading during rotary operations, reducing wear on kelly bars and reducing the chance of mechanical fatigue during structural rock cuts.

The SK666 Micro Pile Drilling Rig is a versatile engineering drilling machine that combines high efficiency, flexibility, and stability. It is specifically designed for large-diameter, high-precision drilling operations. Widely used in micro pile, photovoltaic hole, anchor bolt hole, casing hole, and blasting hole construction, it offers excellent geological adaptability and operational convenience, significantly enhancing construction efficiency and hole quality.
The hydraulic splitting machine utilizes high-pressure hydraulic oil as its power source, applying advanced oblique wedge principles to generate splitting forces ranging from hundreds to thousands of tons. This industrial-grade equipment can effortlessly split massive boulders within seconds, efficiently separating hard ore from rock formations.
TR60 rotary drilling is a new designed self-erecting rig, which adopts advanced hydraulic loading back technology and integrates advanced electronic control technology. The overall performance has reached advanced standards. The corresponding improvement on both structure and control makes the structure more simple and compact, the performance more reliable, and operation more humanized.
Suitable applications: Drilling with telescopic friction or interlocking Kelly bar (standard supply); Drilling with CFA (Continuous Flight Auger) application (optional).
Key Geotechnical Applications:
The drilling rig is suitable for urban underground space, subway, highway, bridge, roadbed, dam foundation and other industrial and civil building foundation reinforcement projects, water blocking and leakage prevention projects, soft ground treatment and geological disaster management projects.
The drilling rig can be used for drilling pipe diameter of 89~142mm multi-tube vertical/horizontal construction, but also can be used for general rotary jet (swing spray, fixed spray) engineering construction. Equipped with a 3-ton crane arm, it can effectively reduce labor intensity.
The loader-type piling machine is modified from a loader chassis and is primarily used for small-diameter, shallow-depth foundation projects, especially suitable for drilling and installing utility poles, photovoltaic piles, etc.
SK800 Multi-functional Anchor Drilling Rig: water and gas are dual-use, one machine is multi-purpose. It is suitable for anti-floating anchor, anchor cable anchoring, slope support, high-pressure rotary spraying, tunnel grouting, submerged hole into the rock, pit casing, core drilling, miniature piles, steel pipe piles and so on.
SK900 Top Drive Anchor Drilling Rig power head, adopting high power top impact, can achieve the effect of impact drilling without the use of submerged hammer and air compressor, with high torque, high rotation speed and strong power. For sand pebbles, gravel, sandy soil, sand layers and other formations that are easy to collapse the hole, it relies on percussion drilling to achieve rapid drilling and ensure the quality of the hole.
SK680 Top Hammer Drilling Rig is designed according to the needs of the construction environment of front-line customers and the needs of Ø50-90mm small hole diameter. The whole machine is small in size, light in weight, fast in travelling speed, and has strong cross-country ability, which can replace special working conditions that conventional drilling rigs cannot operate.
Suitable for: static explosion, small hole diameter drug explosion, such as underground mining, underground construction pits, urban construction sites, tunnels, and other rock drilling environments.

Professional insights for project managers, engineers, and machine operators dealing with high-torque rocky excavations.
We construct the main barrels using high-strength Q345B carbon steel or custom Q460C alloy steel. The high-wear flight areas are reinforced with NM400 or NM500 abrasive-resistant plates, guaranteeing structural integrity under intense rotational forces.
Single-start augers are ideal for loose gravel and soft rock formations as they provide larger clearance for quick chip extraction. Double-start rock augers are essential for medium to hard bedrock, as they distribute the cutting loads evenly across two flights, preventing drill rig wobble.
Yes. We manufacture standard kelly boxes in configurations of 130mm, 150mm, and 200mm to ensure compatibility with major global rig brands. Custom interface adapters can also be fabricated to match unique machine requirements.
We offer specialized RP4 pilot bits, fishtail pilot bits, or tri-cone roller pilots depending on the compressive strength of the target formation. Roller pilots are recommended for rocks with high Unconfined Compressive Strength (UCS > 100 MPa).
Hardfacing involves welding a layer of high-chromium alloy onto the steel flights. This layer acts as a sacrificial barrier against abrasives, preventing direct friction wear on the structural core steel and reducing downtime on-site.
