API Urusyo rwinyo IADC217 12 1/4 santimetero (311mm) yo gucukura neza

Tricone bit nigikoresho cyingenzi cyo gucukura peteroli, imikorere yacyo izagira ingaruka kuburyo butaziguye ubwiza bwo gucukura, gukora neza no kugiciro. Gucukura peteroli no gucukura geologiya nibyo bikoreshwa cyane cyangwa biti. Igice cya cone gifite ingaruka zo kunyeganyega, kumenagura no kogosha urutare ruba ruzunguruka, bityo biti ya cone irashobora guhuzwa nuburyo bworoshye, buciriritse kandi bukomeye. Cyane cyane muri jet cone bit na nozzle ndende nyuma yo kugaragara kwa biti ya cone, umuvuduko wo gucukura biti ya cone umuvuduko wateye imbere cyane, ni amateka yiterambere rya cone bit revolution ikomeye. Bitike ya cone irashobora kugabanywamo amenyo (iryinyo) kubwoko bwinyo, iryinyo (bit) (iryinyo ryashizwemo amenyo ya karbide) biti; ukurikije umubare w amenyo arashobora kugabanywamo cone imwe, kabiri, eshatu-cone na biti nyinshi. Murugo no mumahanga koresha byinshi, ibisanzwe ni Tricone bit.
