Abstract

See full text

A reaming tool includes a tubular body having an axial cavity and a plurality of housings. Each of the housings has an opening through a periphery of the tubular body. A cutter element is positioned in each of the housings, and the cutter element is movable between a retracted position and an extended position. A drive mechanism is positioned within the tubular body and is movable relative to the tubular body to extend or retract each cutter element. A gap is defined between the drive mechanism and the tubular body. A carbon nanotube forest is coupled to one of the drive mechanism and the tubular body to reduce or prevent accumulation of particles in the gap.
