YN27C Gasoline Rock Drill Rock Drilling Tools with Shank Size Hex 22*108
The YN27C gasoline rock drill is a petrol-driven machine that operates without an air compressor. This highly efficient tool features a compact structure, minimal vulnerable components, and simple controls. Ideal for locations without water or electrical power, it combines a gasoline engine, air pump, rock drill, and rotation equipment into one portable unit suitable for breaking, percussive drilling, and tamping operations.
