Integral blade stabilizer is an important tool in the drilling engineering to control the well deviation. It can stabilize the drilling tools in the drilling process of oil, gas and geological exploration. It can increase the bit life, drilling speed and well bore quality. There are two kinds of integral stabilizers: spiral integral blade stabilizer and straight integral blade stabilizer.
Hardfacing type: HF1000, HF2000, HF3000, HF4000
