Umutanga biti bya API IADC217 8 3/4 santimetero (222.2mm)

Bitewe n'ibikoresho byo gukata, imashini zo gucukura zifite utubumbe dutatu zishobora kugabanywamo imashini zo gucukura za TCI n'imashini zo gucukura amenyo y'icyuma.

Irindi zina ry'imashini icukura amenyo ya tri-cone y'icyuma ni imashini icukura amenyo ya tri-cone kuko amenyo yayo akorwa n'imashini icukura kandi ubuso bw'imashini bukozwe muri tungsten carbide hardfacing. Imashini ya tri-cone y'icyuma ifite amenyo maremare kurusha TCI tri-cone bit, bityo ikaba ishobora gucukura imiterere yoroshye kuri ROP nyinshi.
Mu mishinga yo gucukura peteroli, ROP yo gucukura mu buryo buciriritse ishobora kugera kuri metero 30 mu isaha.

Tumaze imyaka 15 n'ibihugu birenga 30 dukora mu buhanga mu gucukura, twatanze uduce two gucukura n'ibikoresho bigezweho byo gucukura mu buryo butandukanye. Muri ubwo buryo harimo ibikomoka kuri peteroli, gaze, ubushakashatsi mu bya jiyo, gucukura, ubucukuzi bw'amabuye y'agaciro, gucukura amariba y'amazi, HDD, ubwubatsi n'ishingiro.

Kubera ko dufite uruganda rwacu rwemewe na API na ISO, uduce dutandukanye tw’uduce dushobora guhindurwa kugira ngo dukore ibintu bitandukanye. Niba ushobora kuduha ibintu byihariye nko gukomera kw’amabuye, ubwoko bw’icyuma gicukura, umuvuduko wo kuzunguruka, uburemere bw’uduce n’imbaraga, dushobora gutanga igisubizo cy’umuhanga mu by’injeniyeri. Bidufasha kandi kubona agace kakubereye iyo utubwiye ibijyanye no gucukura mu buryo buhagaze cyangwa mu buryo butambitse, gucukura amariba y’amavuta cyangwa kudacukura cyangwa gushyiramo ibintu byinshi.
