Tlhaloso ea fatše:
Karolo ea tricone ea IADC115 e loketse majoe a bonolo, a sa kopaneng hantle le libaka tse sa tsitsang tse kang mafika a mokoetla a marl, letsoai, gypsum le mashala a thata, letsopa le majoe a lehlabathe a sa kopaneng hantle,
Li-tricone bits li na le mofuta oa Tungsten Carbide Insert (TCI) le Mill Tooth (Steel Tooth) ho latela thepa ea ho seha.
Li na le mekhoa e mengata 'me li ka seha mefuta e mengata ea libopeho. Karolo ea ho phunya tricone ea leino la leloala e sebelisetsoa libopeho tse bonolo. Li-tricone tse potolohang tsa TCI li sebelisetsoa libopeho tse mahareng le tse thata. Libopeho tsa majoe a bonolo li kenyelletsa lehlabathe le sa kopanngoang, letsopa, majoe a mokoetla a bonolo, libethe tse khubelu le shale. Libopeho tse mahareng tse thata li kenyelletsa li-dolomite, majoe a mokoetla, le shale e thata, ha libopeho tse thata li kenyelletsa shale e thata, ha libopeho tse thata li kenyelletsa shale e thata, majoe a seretse, majoe a mokoetla a cherty le libopeho tse thata le tse khorofo.
