Ipayipi lokubhoboza liwumshini obalulekile kakhulu wemishini yezimayini. Ipayipi lokubhoboza kanye ne-drill bit kuyizinto ezisebenzayo zokubhoboza ngamatshe, ezinomthelela omkhulu ekusebenzeni kahle kokubhoboza ngamatshe.
Ipayipi lokubhoboza, elaziwa nangokuthi insimbi, ngokuvamile lenziwa ngensimbi yekhabhoni, ingxenye igobile i-hexagonal noma i-prototype. Inhloso yalo mgodi iwukususa impuphu yembobo yesibhamu.
Ukuma kwe-drill kukhethwa ngokuya ngobulukhuni nokwakheka kwedwala. Kunezinhlobo ezintathu zezingcezu zokubhoboza ezivamile: i-single chisel, i-double chisel kanye ne-cross. Ama-double - chisel kanye ne-cross - drills angasetshenziswa edwaleni elijwayelekile.
Kunezindlela ezimbili zokuxhuma i-drill pipe bit. Enye inhlanganisela ye-drill pipe kanye ne-drill bit (eyaziwa nangokuthi i-drill), ingasetshenziswa kuphela uma idwala lilukhuni, ngakho-ke ikhanda le-fiber kulula ukuligqoka. Ngalesi sikhathi kufanele kube ne-moton bit ezokwenziwa, eyaziwa ngokuthi i-forging fibre noma i-change drill. Enye ipayipi le-drill elixhunywe ku-bit ngentambo noma i-taper, evame ukusetshenziswa edwaleni eliqinile. Unqenqema lwe-bit lufakwe ngensimbi yethuluzi le-carbide, eyaziwa nangokuthi i-alloy bit. Inzuzo yalolu hlobo lwe-drill ukuthi i-drill ingasuswa futhi ishintshwe nganoma yisiphi isikhathi ngemva kokugaya, futhi ipayipi le-drill lingasebenza ngaphandle kokushintsha, okuthuthukisa ukusebenza kahle komsebenzi, konge insimbi, futhi kunciphisa izindleko zokulungisa i-fiber.
I-drill bit kanye ne-drill pipe kusetshenziswa ndawonye enqubweni yokubhoboza. Uma ubhoboza, sebenzisa i-drill pipe emfushane kanye ne-drill bit enkulu ukuvula imbobo kuqala, bese ufaka kancane kancane i-drill pipe ukuze usebenzise i-drill bit encane, ukuze i-drill bit ibe nkulu kuqala bese kuba ncane, incishiswe kancane kancane iye ku-open edingekayo, i-drill pipe kuqala ibe mfushane bese kuba yinde, ngayinye ngayinye ukuze ushintshe ubude bube ukujula okudingekayo.
