All pneumatic tools require some oil in the airline to lubricate the inner moving parts and reduce the wear between them, cooling them and reducing friction. Rotation units (in rock drills) without oil fail after short time.
Rock Drill Air-Oil is a semi-synthetic lubricant that increases machine reliability and service life by offering superior protection against machine wear and corrosion. Specially developed for Atlas Copco BBC, BBD and RH pneumatic Rock Drills, is also suitable for AY pneumatic pokers with an air line lubricator.
