I-drill yedwala elinomlenze womoya incike emoyeni ocindezelwe ukuze iqhube i-piston ukuze ibuyisele. Ngesikhathi sokushaya, i-piston ishaya umsila we-shank, futhi ngesikhathi sokushaya okubuyayo, i-piston iqhuba ithuluzi lokubhoboza ukuze lijikeleze ukuze kufezwe ukuchoboza nokubhoboza idwala. Ukusetshenziswa kwemishini yokubhoboza egcwele ye-hydraulic ukuze kuthathelwe indawo ama-drill edwala elinomlenze womoya kuyindlela engenakugwenywa ekuthuthukisweni kwe-tunneling yedwala lezimayini zamalahle. Kodwa-ke, okwamanje, imigudu yamadwala engaphezu kuka-90% iqhutshwa kakhulu ukubhoboza idwala elinomlenze womoya. I-drill yedwala elinomlenze womoya iwumkhiqizo ophethwe ngesandla, osebenzisa imishini eminingana (esetshenziswa ngesandla, enyakazayo ngesandla) onenani elikhulu nobubanzi. Ukusebenza nokugcinwa kwayo kulula, futhi intengo iphansi.
