E na le karolo e ts'oanang e ts'oanelang ho khutlisetsa botlaaseng ba casing. 'Me karolo e 'meli ea "percussion" e na le lintlha tse peli tse tsitsitseng: pilot pilot bit, 'me ka morao ho na le eccentric reamer bit e ts'oanelang ho atolosa bophara ba sekoti nakong ea ho cheka. Ka mor'a eccentric bit ke sesebelisoa sa tataiso se kenyang seeta se khethehileng sa mahetla se ka hare ho tlase ho ODEX casing. Ka hona, ODEX e huloa fatše ke khoele ea ho phunya ha lesoba le ntse le tsoela pele. Li-cuttings li phunyeletsa lekhalo la annulus pakeng tsa sesebelisoa sa tataiso le seeta sa casing ho ea ho swivel e li tsamaisang fatše kapa ho se bokellang mohlala.
