Kwinkulungwane yesi-2 BC, iTshayina isebenzise abasebenzi kwaye yasebenzisa amandla e-bamboo bow elastic ukwenza i-cone drill bit ichaphazele umhlaba xa ugrumba. Kamva, yasetyenziswa kwiindawo zasemaphandleni zaseTshayina ixesha elide. Kwakungekho de kwaba ngeminyaka yoo-1950 apho iirigi zokugrumba zentambo yentsimbi zaziswa zivela kwamanye amazwe. Ekuqaleni kweminyaka yoo-1960, iirigi zokugrumba amanzi ezilula ezifana nee-pot cones ezinkulu nezincinci kunye nee-punch-grab cones zaphuhliswa. Malunga nowe-1966, kwaqalwa ukuphuhliswa kwe-positive circulation rotary drilling rig, i-reverse circulation rotary drilling rig kunye ne-compound drilling rig zaphuhliswa ngempumelelo malunga nowe-1974, kwaye i-down-the-hole vibrating rotary drilling rig yenziwa ngasekupheleni kweminyaka yoo-1970. Amazwe aseYurophu naseMelika ayesebenzisa kakhulu iirigi zokugrumba zentambo yentsimbi ngenkulungwane ye-19. Ngeminyaka yoo-1860, iFransi yaqala ukusebenzisa iirigi zokugrumba ze-rotary rotary, ezathi kamva zaziswa eMelika zaza zaphuhliswa ngokukhawuleza. Ngeminyaka yoo-1950, kwaqalwa ukuphuhliswa kweerigi zokugrumba ze-rotary rotary rotary rotary. Kamva, kwavela izixhobo zokubhola ezijikelezayo ezijikelezayo kusetyenziswa umoya ocinezelweyo endaweni yodaka njengendawo yokuhlamba amanzi. Kwiminyaka yoo-1970, kwaveliswa izixhobo zokubhola ezijikelezayo ezijikelezayo ezisebenzisa iintloko zamandla e-hydraulic.
