In engineering, there are often hard bedrocks, large flow stone layers and hard permafrost layers.
It is difficult to drill directly with a mud rotary drill bit. It is necessary to cut the ring groove with a core barrel first, and then drill a hole with a rotary drill bit.
It can greatly increase the drilling speed. The cutting teeth can be bullet teeth or cones. Core barrels with bullet teeth are used in soft formations and permafrost. Core barrels with cones are used in hard formations.
