Warshadda qodista oo dhan IADC127 6 1/4 inji (158.8mm)

Sida laga soo xigtay qalabka jarista, saddex koon oo bit ah ayaa loo qaybin karaa TCI bit iyo Milled Tooth Bit.
Birta tricone-ka ilkaha ee birta ah waxay leeyihiin magac kale oo ah tricone ilkaha oo la shiiday maadaama ilkaha ay soo saaraan mashiinka wax lagu shiido, dusha sare ee koonkana waxaa si adag u wajahda carbide tungsten.

Markaad doorato qalab qodis oo BARIGA FOG, waxaad heleysaa qaybta saxda ah ee codsiga saxda ah, si aad godka ugu sii jiri karto waqti dheer iyadoo safarro yar la sameynayo, kharash yarna lagu bixinayo cag kasta. Maadaama aan si guul leh u farsameyneynay tiknoolajiyaddan in ka badan 15 sano, waxaan ku kalsoonnahay dhaxalkeenna iyo in uusan jirin wax soo saare kale oo qodis ah oo la mid noqon kara khibraddeenna.
Far Eastern waa warshad ku takhasustay qodista bits, sida bits tricone, bits PDC, furitaanka godka HDD, goynta rullaluistemaadka aasaaska ee codsiyada kala duwan.
Annagoo ah warshad hormuud u ah qodista biraha qodista ee Shiinaha, kordhinta cimriga shaqada biraha qodista ayaa ah yoolkeenna. Waxaan had iyo jeer isku daynaa inaan horumarinno biraha leh heerarka gelitaanka sare.
