1 the YN27 type hand-held internal combustion rock drill is made by a small gasoline engine, compressor, rock drill Trinity combination of hand-held drilling tool. 
 2, the use of aircraft operating convenience, the more time-saving, labor-saving, with chisel-speed, high efficiency characteristics. 
 3, it now stands at the class level of similar products, and similar parts completely interchangeable. 
 4, on the rocks perforated vertically downward, level up less than 45 ° vertical down the deepest drilling up to six meters. 5, host weight only 27 kg, and easy to carry, for the mountains, no power is particularly suitable for the region of the pressure equipment and temporary works of greater mobility. 
 6, both in the mountains, plains, and can work both in the heat of the 40 ° or 40 ° below zero cold regions, this machine has a wide range of adaptability. 
 Use 
 The YN27 type applies to the perforated rock, can be changed to a crusher and tamping machine to replace a few parts for a variety of broken shovel chisel, digging, splitting and tamping work. 
 Whether in the mountains, plains; can work both in the heat of the +40 ° C or -40 ° C cold region. The machine has a wide range of adaptability.
