DTH hammers require proper rock drill oil to protect internal components and maintain efficient air seals. Roschen recommends Losonsafe® Rock Drill Oil (RDO) for optimal performance and extended component life. Oil consumption depends on air volume and conditions, with doubled amounts recommended for wet drilling conditions.
