V- Series
V-Series
DANV's new patent (V-Series) is a hybrid that once the seal fails, the bit reverts to an air-bearing product, which will extend the total bit life. This provides longer rotating hours than typical sealed-bearing products. This new patent is especially effective in tough drilling conditions and hard rock applications such as iron ore where high pulldown is required. This hybrid is also extremely successful for applications with excessive groundwater.
Specifications
These bits vary in size depending on ground conditions and client needs.
We make from 6-3/4" (171mm) to 16" (406mm) from hard to soft formation designs.
