Wholesale API 12 1/4 inches milled tooth roller cone bit IADC127G sealed bearing for building HDD rock reamers in the stock from China OEM manufacturer. 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. Operating Parameters The milled tooth roller cone bit is used for drilling soft formations with low compressive strength and high drillability, such as mudstone, gypsum, salt, soft limestione, etc.
