Ukubhoboza nokubhoboza Imithombo nokuqedela ipayipi lomthombo, ukuhlanza kanye nokunye ukusebenza kwemishini.Kubandakanya okokusebenza kwamandla kagesi kanye ne-drill, ipayipi lokubhoboza, ipayipi eliwumgogodla, indawo yokubhola, njll. Umshini wokudlulisa amaphuzu ajwayelekile, umshini wokumba umthelela kanye nomshini wokudlulisa okuhlanganisiwe izigaba ezi-3.
Ngekhulu lesi-2 BC, iShayina yavele yasebenzisa izisebenzi kanye ne-bamboo bow amandla anwebekayo ukwenza i-conical drill ibe nomthelela phansi ukuze ibhoboze umshini wokuzibhoboza wakudala, owawusetshenziswa emaphandleni aseShayina isikhathi eside.Kuze kube yiminyaka yawo-1950, ukwethulwa komshini wokubhoboza izintambo zezintambo ezivela phesheya, ekuqaleni kwawo-1960 kwaqala ukwakha isigaxa esikhulu, esincane sebhodwe, i-grab cone nokunye okulula kokumba umthombo.Ngaphambi nangemva kuka-1966 kwaqala ukwakha umshini wokubhola ojikelezayo, ngo-1974 ngaphambi nangemva kokuthuthukiswa okuphumelelayo komshini wokumba ojikelezayo ojikelezayo kanye nomshini wokumba oyinhlanganisela, ukuphela kweminyaka yama-70 kwakha umshini wokubhola ojikelezayo.I-Europe kanye ne-United States ngekhulu le-19, ukusetshenziswa okuyinhloko kwe-drill yentambo yomthelela wezintambo, ngawo-1860, eFrance kuqala zisebenzisa i-rotary drill, kamuva yethulwa e-United States futhi bathola intuthuko ngokushesha.Ngawo-1950, kwaqala ukwakha umshini wokumba ojikelezayo ojikelezayo, kwase kuvela onomoya ocindezelwe esikhundleni sodaka njengomshini wokumba ojikelezayo ogeza kahle, ngeminyaka yawo-1970 kwathuthukiswa umshini wokumba ojikelezayo we-hydraulic power head rotary.
