GEX1 - Hydraulic Drifter

The GME GEX1 (also known as "Drifter Hidraulicos" in Spanish) hydraulic drifter is a powerful yet compact hydraulic percussive top hammer rock drill. It has a low profile height and comes with built-in air flushing (water flushing optional). It is specially designed for use with a drilling rig in heavy-duty horizontal drilling applications. These applications include foundation drilling, road cutting, trenching, bolting and line drilling in dimensional stone quarries. Biodegradable oils can be used for both hydraulics and in-shank lubrication to reduce the environmental impact.
