High Reliability Flat Face Profile Casing Shoe Drilling With Long Shelf Life
The diamond impregnated casing/rod shoe is the most commonly used as it has the widest range of application and is generally the most efficient tool for advancing casing/rod through overburden layers. We supplies casing and rod shoes with four waterway channels or multi waterway channels depending on the requirements.
We manufacture two types of Casing shoe: W-profile, Flat face profile, and can be customized .
Casing shoe and Rod shoe
H/WL W-profile Casing shoe (117.48mm/99.7mm),The DCDMA standard impregnated diamond bits are the most commonly useful bits in the mineral exploration.
