Inyo rya API ryaciwe uduce dutatu tw'udupira IADC217 dufite santimetero 190 (7.5 mm) mu bubiko

Uduce twa TCI tricone, Uduce twa TCI roller, agace ka roller, agace ka roller y'amenyo y'icyuma, agace ka roller ya TCI, agace ka tricone ya TCI
Igice cya tricone ni igice cyo gutobora gifite umutwe ugabanyijemo ibice bitatu by'ingenzi. Igice cya Thetricone kigizwe n'udutsi dutatu tuzenguruka dukora imbere muri buri kimwe kandi buri kimwe gifite umurongo wacyo w'amenyo yo gukata.
Mu gihe ukoresha iki gikoresho cya tricone drill bits, kigomba gushyirwa kuri cone drill. Ingufu zitangwa n'umutwe wa tricone bits drill zituma bit izenguruka vuba, hanyuma igatobora buhoro buhoro mu gice cy'inyuma n'ibintu. Hamwe n'ubukana bwa tricone rock bit hamwe n'umuvuduko wo kuzenguruka, tricone bit yo gucukura umuvuduko izahinduka. Igitutu kinini cyane cya bit, hanyuma bit pressure izagira ingaruka ku kintu, cyaba ibuye cyangwa ibumba cyangwa ibindi bintu bizajugunywa ku rundi ruhande hamwe no kuzunguruka kwa bit, hanyuma hagakorwa iriba. Iyo bit ikoreshejwe mu kazi, ishobora kurangizwa atari mu gikorwa kimwe, ahubwo mu gikorwa kimwe. Koresha igihe, hanyuma uhagarare kugira ngo urebe kandi ukore.
1. Ingano zavaga kuri 3 7/8" kugeza kuri 26"
2. Ifite kode hafi ya zose za IADC. 3. Ubwiza bwizewe n'igiciro gikwiye
