I-drill yedwala ephethwe ngesandla yethulwa yi-Ingersoll-RandCo. ngo-1912. Ngokwesimo samandla, ihlukaniswe ngezigaba ezine: i-pneumatic, i-hydraulic, i-electric kanye ne-internal combustion drive. Ama-pneumatics yiwona asetshenziswa kakhulu. Ama-drill edwala aphethwe ngesandla afanelekela ukubhoboza ama-blasthole aphansi noma athambekele, ama-blasthole amakhulu okuchoboza okwesibili, imigodi yamabholidi (imigodi engajulile eqondile), kanye nemigodi ye-pulley eqinile (imigodi engajulile evundlile) e-ore eqinile ephakathi nendawo nangaphezulu. Ububanzi be-drill buyi-19 ~ 42mm, kanti ukujula okukhulu kwembobo kungama-5m, ngokuvamile kungaphansi kwama-2.5m. Ama-drill edwala asetshenziswa ngesandla asetshenziswa ngomoya anamandla okuthinta angu-15 ～45J, imvamisa yokuthinta engu-27 ～36Hz, i-torque yokudonsa engu-8 ～13N·m, ingcindezi yokusebenza engu-0.5 ～0.7MPa, ukusetshenziswa komoya okungu-1500 ～3900L/min, kanye nesisindo esingu-7 ～30kg.
