style

Pilot conditioning section improves tool stability & by stress relieving the formation with this intermediate stage, drilling the larger hole can be done at a more aggressive ROP

Drill collar connections allow flexible drillstring placement to optimize reamer and BHA performance.

Both the pilot hole section and the reamer cutting structure contain PDC inserts & carbide hardfacing on gauge to maintain hole integrity and extend tool life.

Short gauge length improves directional responsiveness without compromising hole integrity or tool stability.
