IADC127 12 1/4 Milled Tooth Roller Cone Bits for Building HDD Rock Reamers
Product Description
Milled Tooth Roller Cone Bit is only for drilling soft rocks or mudstone that combined with sticky composition, TCI ( tungsten carbide inserts ) tricone bits can not drill very soft formations due to slow penetration rate(ROP) and bit-balling.
Milled tooth roller cone bits is mainly used for HDD crossing in mudstone and harder interbed that barrel reamer can not pass through and TCI rock reamer easily being bit-balling.
