Models: RT1, RT2 Shark teeth with slanted cutting face. Brazed carbide tip on 42CrMo steel body. Features: Strong scraping performance for clay, mud and sandy soil. Application: Horizontal directional drilling, matched with BR bullet teeth.
Models: DT50, DT87 Heavy-duty block carbide teeth for hard formation. Large brazed carbide insert for rock cutting. Features: Outstanding impact and wear resistance for cobblestone, hard rock and concrete. Application: HDD reamer, foundation drilling in hard and rocky ground.
ZZST Rock Reamer is a purpose-built horizontal directional drilling (HDD) reaming tool designed for maximum penetration and longevity in abrasive hard-rock strata. Featuring patented Shark Bite™ tooth geometry and precision-welded 100% virgin tungsten carbide inserts on a forged 42CrMo steel body, it delivers superior cutting efficiency, exceptional wear resistance, and structural integrity under sustained heavy-load conditions. Ideal for contractors tackling granite, basalt, or quartzite formations where conventional reamers fail prematurely.
Manufactured by Zhuzhou Site Cemented Carbide Co., Ltd.—a leading Hunan-based tungsten carbide specialist—this reamer undergoes rigorous metallurgical validation and field-proven testing to ensure consistent performance across diverse geological profiles. Each unit is engineered for rapid interchangeability and long service life, reducing downtime and total cost of ownership per meter drilled.
Aggressive, asymmetrical tooth profile with reinforced cutting edges delivers up to 35% faster reaming in hard rock while minimizing vibration and bit walk.
Hot-forged alloy steel body ensures optimal hardness-toughness balance (HRC 42–46), resisting bending, cracking, and fatigue under extreme torque loads.
Vacuum-brazed WC teeth at >1150°C guarantee bond strength ≥1200 MPa — eliminating premature tooth loss even in fractured rock.
Granite, basalt, gneiss, quartzite — optimized for ROP >1.2 m/hr at 12–25 rpm and 8–15 kN thrust.
Water, gas, fiber optic, and power lines beneath highways, rivers, and railways where bore accuracy and tool reliability are critical.
Soil-rock mixed zones requiring adaptive cutting force and resistance to chipping under variable load conditions.
