It can receive high WOB in the conventional drilling.It is suitable for various formations by matching cutting
structure with different tooth shape ,tooth density and tooth exposure height.
| IADC | WOB(kN/mm)(bit dia) | RPM(r/min) | Applicable Formations |
| 417 437 447 | 0.35--0.9 | 150--70 | Very soft formations with low compressive strength and high drillablility ,such as clay, mudstone,chalk ,gypsum,salt, soft shale soft limestone,etc |
| 517 527 | 0.35--1.0 | 140--60 | Soft formations with low compressive strength and high drillablility such asmudstone,gypsum,salt,soft shale,soft
limestone ,etc. |
| 537 547 | 0.45--1.0 | 120--50 | soft to medium formations with low compressive strength ,such as medium soft shale ,medium soft limestone,medium soft limestone,medium soft sandstone,medium formation with harder and more abrasive interbeds.etc |
| 617 627 | 0.45--1.1 | 90--50 | Medium hard formations with high compressive strength such as hard shale.limestone,sandstone,dolomite,etc |
| 637 | 0.5--1.2 | 80--40 | Hard formations with high compressive strength,such as sandstone,limestone,dolomite,hard gypsum,marble,etc |
Note:the upper limits of WOB and RPM in above lable should bot be used simulancously
