Abstract

Rock drilling unit (1) with a thread (4) for being able to create a threaded connection to a drill unit (13) with a second thread (10). The rock drilling unit and the drill unit include means (8,15,9,16) for creating, after joining together of the units, a tight space comprising the threaded connection, and a duct (5) via which that space can be pressurised with a fluid before parting of the connection. A rock drilling rig including such rock drilling unit and/or drill unit is also described. A method for parting a threaded connection between such a rock drilling unit and drill unit is also described.
