Drill bit Parameters | |||
Tri-cone bit type | 4 3/4'' 126 | Diameter | 120.7mm |
IADC | 126 | API Pin Connection | 2 7/8'' API REG |
WOB(KN/mm) | 0.35~1.00 | RPM(r/min) | 150~70 |
Applicable Formation | Soft with low compressive strength and high drillability, such as shale, clay, salt bed and soft limestone, etc. | ||
Features | This bit can sustain higher WOB under normal rotary speed. | ||
Note: the upper limits for the bit weight and rotary speed recommend in the table can not be used at the same time. |
