I. Description and Application

YN27C, an independent impact function Rock Drill, which can be used for
cleaving rock, bruising the concrete foundation, tamping the railroad bed, small area tamping by combining with auxiliary means.
Therefore, it changes the traditional working method of rock drill, which was only used to drill blast holes.
So YN27 expands functions of rock drill.

It is a very efficient machine with very compact structure, that few wearing parts, and very easy to control, 
composed of gasoline engine, Air pump, rock drill.

It adapts to these outside situations without water and electronic power.
Meanwhile it is a hand- held drill, during operation, rock power is blown away by the compressed air produced by the machine itself.

Its suited to work on high mountains, plains, hot and cold area with no power and no water supply and air compressing equipments, and especially suits the projects that the machine has to be carried at any time and in any area. 

It has functions of drilling hole, cleavage, bruising, tamping and chiseling.
It is widely used in mine, road construction, quarrying, national defense works, etc.

II. Advantage:

1)Portable, light – only 27kg easy to carry, and easy to operate, just turn the handle to make it work. 
2)Time and labor saving, Drilling fast and high efficiency. 
3)First-class level Drilling Tools, suitable for site without power or pressure equipment, it has wide adaptability for high mountain and plain, extreme temperature (40 to -40) 
4)Used to drill vertical downward hole(max depth 6m) and <45° upward hole.
