Portable core drill has been primarily used for precious metals and basic metals investigation since it was invented. The handheld drill has been found to be best used as a near-surface initial scanning and mapping tool, often in conjunction with handheld xrf field analyzers.when mineral enrichment is discovered by these means larger drilling equipment can then be efficiently employed to establish vertical definition.Also, portable core drill was used for a variety of projects including petroleum source, reservoir, cap rock investigations, paleomagnetic studies, hydrogeologic investigations including monitoring well installations by academic investigators.Whats more, the handheld core drill has been used for steel fence post in rock installation, concrete and rock demolition with the use of explosives or expanding concrete (.
