M6 HDD
Fit for purpose, built for success
The Wenzel horizontal directional drilling (HDD) oil sealed drilling motor is designed to offer reliable performance for both straight and directional drilling within the oil and gas industry, as well as for civil construction applications that require trenchless HDD.
Built on our highly successful M6 oil sealed bearing assembly, our HDD motor includes a shortened driveline and a large bit box mandrel developed specifically for our HDD customers.
- High allowable weight on bit (WOB) and load capacities.
- Equipped with 2º fixed bend or optional adjustable bend assembly.
- Large bit box mandrel.
- Features Wenzel’s HDD-specific driveline, which shortens the overall length of the motor.
- In-house manufactured components adhere to Wenzel’s high standard of premium materials and quality production.
