HQ PQ Diamond Reaming Shell For Geological Core Drilling
AQ/BQ/NQ/HQ/PQ Diamond Reaming Shell For Geological Core Drilling
Reaming Shells are used to maintain the critical hole diameter and to stabilize the drilling system in the hole during operation. The reaming shell is part of an overall drilling system that includes a core bit, a core capture mechanism (the core barrel assembly), the drill string (rods), and the drill rig itself.
1. Maximum active surface helps limit deviation
2. Surface-set synthetic diamond ring
3. Reinforced arrow tip pattern situated at the angle of contact with additional TSP diamonds provides greater protection.
