API na ISO tricone roller bit IADC537 26″ (660.4mm)

Dukurikije ibikoresho byo gukata, icyuma cya tirocne gishobora kugabanywamo icyuma cya TCI na icyuma cya Steel Tooth Bit.
TCI ni mu magambo ahinnye ya Tungsten Carbide Insert, tungsten carbide ni ibikoresho bikomeye bisanzwe mu murima wo gucukura amabuye, ikindi gikoresho ni diyama.
Injiza bivuze amenyo ya Tungsten Carbide ashyirwa ku migozi y'uduce duto two gucukura tworoshye. API TCI tricone drill bit. Ihuza ry'umugozi wa API wa IADC537 26" ni pin 7 5/8 reg. Ku bunini bwa tricone bit ya 26", twita kandi 660mm tricone bit.

Ibice byacu bifite ubwoko bwa Rubber / Elastomer bearing sealed bearing na Metal sealed bearing. Turasaba ko twahitamo ibice by'icyuma bifunganye ku maso ku mariba maremare afite imiterere ikomeye. Ku bijyanye no gucukura amariba maremare cyane, turasaba ko uduce twa tricone bearing sealed bearing twa Metal-face sealed bearing dufite uburebure burenga metero 1000, Ku bijyanye no gucukura imiyoboro y'icyitegererezo idafite amabuye maremare n'uburebure burenga metero 300, turasaba kandi ko uduce twa tricone bearing sealed bearing twa metal-face sealed bearing. Ku bijyanye no gucukura amazi, gucukura amariba maremare cyangwa imishinga yo gucukura imiyoboro y'icyitegererezo idafite uburebure, uduce twa tricone bearing sealed bearing twa elastomer (rubber) dufite igiciro cyiza.
