Product Description

Cone Roller Bit Hdd Rock Reamer Hole Opener For Well Drilling



According to the characteristics of the rig and different methane conditions. We adopt a more suitable tooth type, bearing structure, sealing method and inclination angle of the claws. Water cutting, good sand recovery can effectively reduce sand collection, and the cone is made of heat-coated anti-wear alloy to reduce wear. The unique cone anti-falling design prevents cone falling accidents caused by bearing damage. The perfect welding process prevents damage to the seal and bearing system due to over-jumping. The bit body adopts a spiral design, which has good performance of stable sand return, improves the opening speed, and reduces the repeated rock breaking by the cone.




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.

Cutting structure
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 formula and a new cutting structure can improve the wear resistance of the reamer. The helmsman is a tri-cone bit.


Sealing and lubrication
High-performance HNBR o-shaped sealing ring for bearing sealing, high-grade grease for lubrication.
