Izinsimbi zokubhoboza ezingenalutho zaziwa nangokuthi izinsimbi zokubhoboza eziwumgogodla, izivula izimbobo, izinsimbi zokubhoboza ezimaphakathi, izingcezu zepuleti lensimbi, izinsimbi zokubhoboza kazibuthe, izinsimbi zokubhoboza ujantshi, njll.
Izinto eziyinhloko zama-drill bits yilezi: insimbi enesivinini esikhulu;i-powder metallurgy;i-carbide enosimende.
Izinsimbi zokubhoboza ezingenalutho zinezinhlobo eziphelele zezinhlobo kanye nokucaciswa kwazo futhi zilungele izinhlobo ezahlukene zokubhoboza izihlalo zikazibuthe (ama-magnetic drill) kanye nemishini yokumba evamile, imishini yokugaya, imishini eyisicefe, njll. Lo mkhiqizo usetshenziswa ngokuhambisana nozibuthe ovela kwamanye amazwe. ukubhoboza, kanye nokusebenza kahle kokubhola izikhathi eziyisi-8 kuye kweziyi-10 kunezinsimbi ezijwayelekile zokubhola.
