Advantages
Best price and high quality
Bearing type: 1. Sealed and unsealed bearings. 2. Metal seal journal bearing. 3. Rubber seal journal bearing
Cutting structure: the rear cone and tooth surface are hardened, which improves the steel tooth profile and welding material, and the tooth surface protrudes higher
Application: Suitable for horizontal directional drilling in rock formation reaming drilling
Our products and services have passed the ISO 9001:2008 and API certification, and the mature production technology ensures that the product quality meets the international requirements.
Features
Cutting structure
