Detailed Product Description

 Features

1. The Internal Combustion Rock Drill Type YN30A is a hand-operated rock-drilling tool, composed of a small petrol engine, an air compressor and a rock drill.
2. During operation, the rock powder is blown away by the compressed air produced by the machine itself.
3. Carrying easily as the main engine weight only 30kg. Suited to work on high mountains, or places with no powersupply and air compressing equipment, and especially suiting the temporary projects because the machine can be carried at any time and any place.
