Isizathu sokuba i-4 3/4 Inch Tricone Bit IADC 117 ibalulekile ekuhlolweni kweoyile

Isizathu sokuba i-4 3/4 Intshi yeBit IADC 117 ibalulekile ekuhloleni ioyile Ukuqonda i-4 3/4 Intshi ye-Tricone I I-ADC 117 ** 4 3/4 intshi ye-Tricone Bit IADC 117 ** sisixhobo se-mbona kwi-oyile yanamhlanje. Le bit idume ngokukwazi kwayo ukungena kwiindlela ezahlukeneyo ngokufanelekileyo, ukwenza ukhetho olukhethiweyo phakathi kweenjineli zomba kunye nabaqhubi. Kodwa yintoni kanye eyenza le particula
