300mm Welding Tapered Roller Reamer Tricone Rock Bit
Introduction
300mm tapered roller reamer Tapered roller reamer is a commonly used drilling tool in rock formation excavation. The tapered roller reamer produced by our company is suitable for all kinds of trenchless drilling rigs, and can be used for the expansion of various rock formations. The specification range is Φ260-1800mm.
Features
The reamer is mainly composed of four or more cones. The use of high-quality tungsten carbide hard surface or high-quality tungsten carbide blade formulations and new cutting structures can improve the wear resistance of the reamer. The pilot is three cone drill bits.
High-performance HNBR O-ring, used for bearing seal, high-grade grease, used for lubrication.
Advantages
Bearing types: 1. Sealed bearings and unsealed bearings. 2. Metal sealed journal bearings. 3. Rubber sealed journal bearings
Cutting structure: all surfaces of the rear cone and teeth are hardened, improving the shape of the steel teeth and welding materials, showing higher teeth
Application structure: low compressive strength and high drillability softness, such as shale, clay, salt layer, etc.
All our activities have obtained ISO 9001:2008 and API certification for products and services. At the same time, mature production technology can ensure that the quality meets international requirements.
