Brief: The core barrel with roller bit can drill the formation which the drilling bucket and core barrel with bullect teeth can not drill on foundation piling project.If you want to cut hard rock, you should have high effective core barrel piling with constrution drilling equipment.

Brief: Regardless of the formation condition,the wear and tear of the roller bits related to its and rotate speed and at the same time, when wear and tear reach to a certain level, the piling efficient would get slow.
