Ngenxa yezidingo ezihlukene zokuma, ukucaciswa, ukunemba, nezindlela zokucubungula izimbobo, kunezinhlobo eziningi zamathuluzi okusika omshini womgodi.

I-drill ephakathi isetshenziselwa ukwakhiwa kwangaphambili kanye nokubeka okunembile kokucutshungulwa kwezimbobo, ukuqondisa ukubhola kwe-Fried Dough Twists ukucubungula izimbobo nokunciphisa amaphutha. Uma imbobo emaphakathi ingabholwanga, kuzoba khona ukuchezuka lapho kubholwa ngokuqondile.

I-Fried Dough Twists drill ibizwa nge-spiral chip groove, efana ne-Fried Dough Twists. I-Fried Dough Twists drill iyithuluzi elivame ukusetshenziswa kakhulu lokucubungula imbobo, elisetshenziselwa ukucubungula izimbobo ezenziwe ngensimbi engagqwali, ingxubevange yethusi ye-titanium nezinye izinto.

I-deep hole drill iwuhlobo lokubhoboza olusetshenziselwa ukucubungula izimbobo ezijulile, ezingahlukaniswa zibe ukukhishwa kwangaphandle nangaphakathi.

Ubunzima bokukhipha ukushisa kanye nokukhipha amanzi ngesikhathi sokumba imbobo ejulile, kanye nokungaqini kahle ngenxa yepayipi elincane lokubhoboza, kungabangela kalula ukugoba nokudlidliza.Ngokuvamile, izinhlelo zokupholisa ingcindezi zisetshenziselwa ukuxazulula izinkinga zokupholisa nokukhipha amanzi.

I-Countersink drill, eyaziwa nangokuthi i-spot facer, iwuhlobo lwe-drill bit enomshini oqondisiwe.

Indlela evamile yokucubungula iwukuba uqale ubhoboze izimbobo eziphansi ngosayizi ojwayelekile wokubhoboza, bese usebenzisa i-countersunk drill ukuze ubhoboze imigodi engashoni ngaphezulu. Ngokuyisisekelo isetshenziselwa ukucubungula ubuso bangaphandle bokuphela kwezimbobo eziphikisayo noma eziyisicaba.

Ingxenye yokusika ye-drill eyisicaba imise okwefosholo, inesakhiwo esilula, esilungele ukubhola ukhokho, ukhuni oluqinile, nezinye izinto eziningi zokhuni.

Unqenqema oluthambekele lokusika lwe-drill flat lunikeza ukusika okusheshayo nokuhlanzekile, futhi amaphuzu aqondile okugaya angathuthukisa ukunemba, kodwa ukusebenza kokusika nokukhipha amanzi akulungile.

I-set drill, eyaziwa nangokuthi i-hollow drill bit kanye ne-drill drill, njengoba igama liphakamisa, i-drill bit engenawo umgogodla wokubhoboza,

Ingafaka ithuluzi lokukhanda imbobo enwetshiwe embobeni engaphakathi ebhoboziwe.

Lapho ucubungula izimbobo ezijulile ezinobubanzi bembobo engaphakathi engaphezu kwamamilimitha ayi-150, indlela yokumba izidleke ivame ukusetshenziswa.

Umzimba we-drill bit ufakwe amabhulokhi omhlahlandlela ukuvimbela ukudlidliza nokuchezuka kwembobo yokusika ngesikhathi sokusika. Amabhulokhi omhlahlandlela enziwe ngezinto ezingagugi njenge-alloy eqinile, ukhuni lwenjoloba, noma inayiloni.
