Diamond + PDC Reaming Shell

Diamond + PDC Reaming Shell

Reamed shells are available for all types of core barrels and drill bits.
The product description
Reamed shells are available for all types of core barrels and drill bits. The
design is the result of years of experience. Reamed shells improve core
recovery and quality by reducing vibration and stabilizing coring. The longer
service life ensures that the aperture remains the same, preventing the new bit
from getting stuck in the narrow hole. The wash channel has been optimized to
keep the diamond cool enough without limiting flow, thus ensuring the lowest
circulating pressure. We are an Diamond Core Bits Exporter.

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
