IADC532 TCI standard open air-cooled roller bearing bit  for soft formations with low compressive strength and high drillability. The compressive strength are as following: 85 - 100 MPA 12,000 - 14,500 PSI The IADC532 tricone bit will be worked medium hard and abrasive rock ,including hard limestone or chert,hematite ores , sandstones with streaks of quartz ,metamorphic coarse grained rocks. CUTTING STRUCTURE:  Conical on gage and inner rows. Designed for medium-soft formations with low compressive strengths such as shale,soft limestone,dolomite with interlayers and coal ore. Application:18,000-27,000Psi
