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.
