ProDrill offers heavy duty tricone bits to meet your customized drilling needs. We have classified the bits based on their diameter (footprint), american petroleum industry number (API Number) and international association of drilling contractor number (IADC number). The IADC number further classifies the tricone bits based on the tooth material of construction, suitability for drilling into soft, medium or hard rock and bearing type used. All possible combinations of IADC number for tricone bits are available at ProDrill.
