Description
Product Application
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.
