API tricone feerka feeraha IDC216 4 5/8 inji (118mm)
Sharaxaada Alaabta
4 5/8 "TCI tricone bit waxaa si weyn loogu isticmaalaa qodista ceelasha biyaha, sahaminta, godka tijaabada HDD, tuujin aasaaska, waxay leedahay naqshadeynta daloolka jet dhexe, sidaas darteed sidoo kale waa la shaqeyn karaa qodista wareegga wareegga.
Xirmada waa la shaabadeeyey, nolosha shaqadu aad bay uga dheer tahay biraha duubka leh ee furan.
Noocaan ah ilkaha birta ah ee loo yaqaan 'tricone bit' ayaa leh dalool dhexe oo ku habboon qodista RC-da (Reverse Circulation drilling).
IADC216 tricone bit wuxuu qodi karaa qaabab ka adag IADC126, doorashada IADC ee ku haboon marka loo eego engegnaanta dhagaxyada waa talaabada ugu horeysa ee waxtarka sare leh.Far Eastern Drilling waa warshad shahaado siisay API oo ah tricone roller bit.
