Ibicuruzwa
API 7-1 gucukura Roller Reamer hamwe Ubwoko B & Ubwoko F & Ubwoko T.
Gusaba ibicuruzwa
Roller Reamer yagenewe ibikorwa bitandukanye byo gusubiramo ariko cyane cyane mubikorwa byo gutuza mugihe cyo gucukura muburyo bubi cyane. Bizahuza ubunini bw'imyobo kuva kuri 4 5/8 kugeza 26inch.Iyongeyeho, buri mubiri muguhindura byoroshye guhagarika no guhitamo neza gukata, bizahuza intera nini yubunini.
Ubwoko bwibicuruzwa
Ubwoko butatu butandukanye (T, F na B) bwo gukata butangwa:
Ubwoko T: Yasya, ikozwe hamwe namenyo akomeye atyaye kugirango yoroshye.
Ubwoko F: Yasya, ikozwe hamwe namenyo akomeye asa neza, kugirango aringaniye.
Ubwoko B: Bifite ibikoresho bikanda kuri tungsten karbide ya buto, kugirango bikorwe.
