Mabowo a Carbide ndi zida zomwe zimagwiritsidwa ntchito kuboola mabowo kapena mabowo osawoneka bwino muzinthu zolimba ndikuboola mabowo omwe alipo. Mabowo omwe amagwiritsidwa ntchito nthawi zambiri amaphatikizapo ma bowo opindika, ma bowo osalala, ma bowo apakati, ma bowo ozama ndi ma bowo omangira. Ngakhale kuti ma reamers ndi ma countersink sangathe kuboola mabowo muzinthu zolimba, nthawi zambiri amagawidwa ngati ma drill bits.
Pakukumba, chobowola chimazungulira mozungulira mzere wowongoka ndikuyenda mozungulira nthawi yomweyo. Dothi limadulidwa pogwiritsa ntchito mphamvu ya torque ndi axial ya chobowola, ndipo limawonongeka ndikusweka pogwiritsa ntchito mphamvu ya extrusion ndi centrifugal ya tsamba logwira ntchito, ndikupanga kayendedwe ka nthaka komwe kamakanikizidwa pakhoma la dzenje, ndipo nthawi yomweyo kumakwezedwa pamwamba pa tsamba. Pamene kayendedwe ka nthaka kasuntha kupita kumalo komwe kulibe khoma la dzenje, dothi losweka limaponyedwa mozungulira dzenje chifukwa cha mphamvu ya centrifugal, ndipo njira yonse yokumba dzenje imatsirizika.
