Umbhobho wokugrumba ngumatshini obalulekileyo kwizixhobo zoomatshini bokwemba. Umbhobho wokugrumba kunye ne-drill bit zizixhobo ezisebenzayo zokugrumba amatye, ezinefuthe elikhulu ekusebenzeni kakuhle kokugrumba amatye.
Umbhobho wokubhola, okwaziwa ngokuba yintsimbi, wenziwe ngentsimbi yekhabhoni, le ndawo inendawo engenanto okanye iprototype. Injongo yomgodi kukususa umgubo wemibhobho.
Imilo yedrill ikhethwa ngokobunzima kunye nokwakheka kwelitye. Kukho iintlobo ezintathu zee-drill bits eziqhelekileyo: i-single chisel, i-double chisel kunye ne-cross. Ii-double-chisel kunye ne-cross-shaped drills zingasetyenziswa kwilitye eliqhelekileyo.
Kukho iindlela ezimbini zokudibanisa i-drill pipe bit. Enye kukudibanisa i-drill pipe kunye ne-drill bit (eyaziwa ngokuba yi-drill), ingasetyenziswa kuphela xa ilitye lilukhuni, ngoko ke intloko yefayibha kulula ukuyinxiba. Ngeli xesha kufuneka kubekho i-moton bit eza kufakelwa, eyaziwa ngokuba yi-forging fiber okanye i-change drill. Enye yi-drill pipe eqhagamshelwe kwi-bit ngentambo okanye i-taper, edla ngokusetyenziswa kwi-hard rock. Umphetho we-bit ugqunywe ngentsimbi yesixhobo se-carbide, eyaziwa ngokuba yi-alloy bit. Inzuzo yolu hlobo lwe-drill kukuba i-drill ingasuswa kwaye itshintshwe nangaliphi na ixesha emva kokusila, kwaye i-drill pipe ingasebenza ngaphandle kokutshintsha, nto leyo ephucula ukusebenza kakuhle komsebenzi, igcine intsimbi, kwaye inciphisa iindleko zokulungisa ifayibha.
I-drill bit kunye ne-drill pipe zisetyenziswa kunye kwinkqubo yokugrumba. Xa ugrumba, sebenzisa i-drill pipe emfutshane kunye ne-drill bit enkulu ukuvula umngxuma kuqala, uze wongeze i-drill pipe kancinci kancinci ukuze usebenzise i-drill bit encinci, ukuze i-drill bit ibe nkulu kuqala ize ibe ncinci, incitshiswe kancinci kancinci iye kwindawo efunekayo, i-drill pipe kuqala ibe mfutshane ize ibe nde, nganye nganye ukuze kutshintshwe ubude bube kubunzulu obufunekayo.
