It can receive higher WOB and faster rotary speed than conventional roller bearing bits .It is suitable for high RPM applications.
Recommended Drilling Parameters
| IADC | WOB(kN/mm)(bit dia) | RPM(r/min) | Applicable Formations |
| 115 | 0.3--0.75 | 200--80 | Very soft formations with low compressive strength and high drillability,such as clay,mudstone,chalk ,etc. |
| 125 | 0.3--0.85 | 200--80 | Soft formations with low compressive strength and
high drillability,such as mudstone,gypsum ,salt,soft shale,soft limestone,etc. |
| 135 | 0.3--0.95 | 180--80 | Soft to medium soft formations with low compressive strength and high drillability.such as medium soft shale,
hard gypsum,medium soft limestone,medium soft sandstone,soft formation with harder interbeds,etc. |
| 215 | 0.35--0.75 | 180--80 | Medium formations with high compressive strength ,
such as medium soft shale,hard gypsum,medium soft limestone,medium soft sandstone,soft formation with harder interbeds ,etc. |
Note:The upper limits of WOB and RPM in above table should not be used simultancously.
