Tci Bits - High Wob Compatibility 0.35-1.2 Kn/mm | Versatile Tooth Structures For Soft To Hard Formations

Our offered range of TCI Bits is available with following specifications :-

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--70Very 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--60Soft 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
