Graphite Powder has a greasy feel and very low coefficient of friction. Chemically, Graphite Powder is the pure form of carbon.
Graphite Powder is used as a torque reducer in directional or crooked holes when a water based mud system is being used. Torque reduction does not become significant until a concentration of 3.0 kg/m³ is exceeded. The optimum concentration is in the range of 6.0-7.0 kg/m³.
