Diamond + PDC Reaming Shell
Reaming shells are available for all types of core barrels and drill bits. The design is the result of many years of experience. Reaming shells improve core recovery and quality due to reduced vibration and stabilized coring. The longer life guarantees that the hole diameter stays true, which prevents new bits from getting stuck in narrowing holes. The flushing channels have been optimized to keep the diamonds sufficiently cool without restricting flow, ensuring the lowest possible circulation pressure.
FEATURES&BENEFITS |
* Maintains hole diameter longer to prevent new bits from sticking |
* Improves core quality due to a stabilized core barrel. |
* Unique design and diamond setting for long service life |
* Flushing channels designed to ensure low circulation pressure |
