Incazelo Yomkhiqizo

I-Metal Face evaliwe i-TCI Drill Bit IADC437 8 1/2" (215mm noma 216mm) ingeyokwakhiwa okuthambile kokumba umthombo.
I-1>8 1/2"(215mm noma 216mm) iwusayizi ojwayelekile lapho kumbiwa khona umthombo ojulile njengowoyela negesi, futhi ingusayizi ojwayelekile wokumba imbobo yokushayela eqondile eqonde ngqo.
Uxhumano lwentambo yi-4 1/2 API REG PIN.
