ABSTRACT:
A drilling attachment for use in wet and dry drilling operations includes a housing having first and second fluid conduits, and a drive shaft mounted within the housing and having fluid transmitting first and second end portions in fluid communication with a respective first and second fluid conduit. In one embodiment, at any time one end of the drive shaft is coupled to a drive unit and the other end of the drive shaft is coupled to a core drill bit. In a dry drilling operation, dust is extracted from the core of the drill bit, is passed through the drive shaft and exits the housing via one of the fluid conduits. In a wet drilling operation, fluid such as water is passed through the other of the fluid conduits, through the drive shaft and into the core of the drill bit.
