Uduce tw'amenyo y'icyuma cya API IADC217 santimetero 215 (8.5 mm) two gucukura amabuye

Ifite icyuma gikoresha icyuma cya Tricone, gifite ubuso bukomeye bw'umutwe, gifite icyuma gikozwe mu cyuma gikozwe mu cyuma gigabanya ubukana hanyuma gishyirwa mu cyuma cya silver. Ubushobozi bwo gutwara imizigo n'ubudahangarwa bw'icyuma gikozwe mu cyuma birushaho kwiyongera.
Ifu ya O-ring ikozwe mu ifu ya buna ifite ubushobozi bwo kwangirika cyane, igice cy’ifu yabugenewe cyongereweho hamwe n’urufunguzo rwo gufunga rwakozwe neza mu gace gafunga ko mu bwoko bwa cone byongera ubwizerwe bw’ifu ya buna. Ifu ya bit bearing irashobora gufungwa neza.
Ku gice cy'amenyo cy'icyuma, ubuso bw'amenyo buba bukomeye kandi bufite ubwoko bushya bw'uburyo bwo kwirinda kwangirika.
Ibikoresho bityo bikamara igihe kirekire cyo gukora cy'inyubako yo gukata mu gihe bigifite ROP nyinshi
----Imiterere yo Gukata
Iryinyo ry'icyuma: Karubide ikomeye ya tungsten ireba hejuru, yongera cyane ubushobozi bwo kwangirika kw'iryinyo.
Udukoresho twa Tungsten Carbide: Udukoresho twa tungsten carbide two mu bwoko butandukanye two mu rwego rwo hejuru dushobora gushyirwa ku bice, by’umwuga kandi
guhitamo mu buryo bwa siyansi ibikoresho byo gucukura hakurikijwe uburyo butandukanye bwo gukoresha no gucukura kugira ngo habeho gucukura neza cyane
umusaruro.
