Overview: It can be connected to the drill string to achieve micro drilling while drilling, expanding the wellbore with a diameter slightly larger than the theoretical diameter of the drill bit.

Applicable: Suitable for formations that are prone to necking and require slight expansion due to irregular diameter.

Technical features:

Single component, without moving parts, with higher strength than the connected drill pipe: the upper and lower cutting structures can achieve conventional forward drilling and reverse drilling during the drilling process, reducing drilling time and number of wellbore passes; Adopting an eccentric structure design, it can expand the wellbore size through a larger diameter than the tool, minimizing or eliminating micro dog legs.

Technical parameters:
