Application of coring buckets:
For the foundation drilling industry, especially in the drilling of karst caves, bailing, etc. The coring bucket is an innovative drilling tool in the foundation drilling industry. The core ring surrounds the hinged bucket that can open and close with a robust cutting edge at the opening of the hinged plate.
It is the hybrid coring bucket that functions well to drill out the bottom of the casing, especially when dealing with water. If there is sloping rock and a need to maintain verticality, the coring bucket provides a cross-cutter to hold the cuttings without having to switch drilling tools for extracting all the cuttings in the hole.
So the coring bucket can be switched between the core barrel to the bucket to complete a pass in the rock. It helps save costs by avoiding multiple tools at the job site.
