Rock drilling tools manufacturer ProDrill provides a full line of rotary drilling tools such as tricone, bicone bits. Tricone bits are available in new and used (re-tip and re-run) steel teeth(ST) and tungsten carbide insert(TCI), size from 3 3/8"(85.7mm) to 26"(660.4mm) for all formations, with any bearing/seal type, and provide a wide range of additional custom features.
The reverse circulation cone bit sucks mud and rock cuttings into the inner cavity of the drill pipe through the water hole of the bit, and then draws it out from the inner cavity of the drill pipe to the ground.
Rock drilling tools factory ProDrill rotary drilling tools manufacture a complete line of tricone, bicone bit which are available in new and used (re-tip and re-run) steel tooth and tungsten carbide insert, size 17 1/2" IADC535(444.5mm) for use in all formations, with any bearing/seal type, and a wide range of additional custom features.

ProDrill offers heavy duty Tricone bit to meet your customized drilling needs. We have classified the bits based on their diameter (footprint), International Association of Drilling Contractor number (IADC number) and American Petroleum Industry number (API 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. ProDrill can offer tricone bits for all possible combinations of IADC number.
