Imyitozo ya chill ni clamp idasanzwe ikoreshwa mugufata kuzunguruka bito; kubera ibi, rimwe na rimwe byitwa bit bitwaye. Mu myitozo, chucks isanzwe ifite urwasaya rwinshi kugirango irinde bito. Muri moderi zimwe, ukeneye urufunguzo rwa chuck kugirango woroshye cyangwa ushimangire igikoma, ibi byitwa urufunguzo. Mu zindi moderi ariko, ntukeneye urufunguzo kandi urashobora kurekura byoroshye cyangwa gukomera igikoma n'amaboko yawe, ibi byitwa chucks idafite akamaro. Imyitozo hafi ya yose idafite umugozi ifite ibikoresho bidafite akamaro. Nubwo gukorana na chucks zidafite akamaro birakunzwe cyane kuberako byoroshye, chucks zingenzi zitanga umutekano cyane cyane kubisabwa biremereye.
