An air-cooled tricone bit having an air conduit corresponding to individual cones of the tricone bit is filled with lubricant or grease with particles therein is disclosed. The grease may include fullerene-like particles, such as tungsten disulfide, molybdenum disulfide, graphene, graphite, or the like. By packing the air conduit of the tricone bit with the grease with particles, the grease with particles may flow during an initial break-in period of the tricone bit to coat the internal components of the tricone bit. This reduces the friction between the internal components of the tricone bit, such as journal bases, cones, and/or bearing elements. The reduced friction between the internal components of the tricone bit result in reduced wear, both during the break-in period and after the break-in period. The reduced wear results in a greater operating lifetime of the tricone bits.
