Umsila we-drill tail screw ukwimo yomsila we-drill okanye umsila otsolo. Akufuneki ukubamba imingxuma kwi-workpiece yokuqala, kwaye inokubhobhoza ngokuthe ngqo, icofe, kwaye itshixe kwizinto zokuseta kunye nesiseko sezinto. Xa kuthelekiswa nezikrufu eziqhelekileyo, isikrufu somsila we-drill Ukuqina okuphezulu kunye nokugcinwa kwamandla, akuyi kukhululeka emva kwexesha elide lokudibanisa, kulula kwaye kukhuselekile ukusebenzisa, ukubhola kunye nokucofa kunokugqitywa kumsebenzi omnye, ukugcina ixesha, abasebenzi kunye nomsebenzi. Izikrufu zokugrumba zisetyenziselwa ukulungisa iipleyiti zetsimbi ezifana neziqhoboshi zentsimbi, ezisetyenziswa ngokubanzi ukutshixa iipleyiti zetsimbi kunye neepleyiti ezingezizo ezentsimbi, ezifana nokulungisa ngokuthe ngqo iibhodi ze-silicon-calcium, iibhodi zegypsum kunye neebhodi zokhuni ezahlukeneyo kwiipleyiti zetsimbi. Izikrufu zokwemba ngoyilo olufanelekileyo kunye nolwakhiwo lunokwenza ipleyiti yentsimbi kunye nepleyiti yokukhwela itshixeke ngokuqinileyo, ukuthintela umonakalo kunye nemikrwelo yepleyiti yokukhwelana, kwaye kulula ukuyifaka.
