Audited Supplier The internal combustion rock drill YN27C is a portable rock-drilling tool, combined of a small petrol engine, an air compressor and a rock drill.
During operation, rock powder is blown away by the compressed air produces by the machine itself.
This machine is a portable machine; it is also can use with supporting stand. Drilling hole diameter 28mm-42mm,when turning vertically down-ward, it can drill to the depth of 6m.
It is easy to be carried along. It is suited to work on high mountains, plains, hot and cold condition with no power, no water supply and no air compressing equipments. Especially, suits the projects that the machine has to be carried at any time and in any area.
Applications
With turning the swing arm to run or stop rotation plumbum,the machine can be converted into a breaker or a hammer, for breaking,digging,splitting or ramming.
The machine is suited to build of bridge, road, powder station, geological exploration etc.
Combined Rock drill/breaker.
Self-contained, Gasoline powered Drill and paving Breaker
Double the function......half the cost!
In the drill mode it produces flushing air for cutting removal, impact androtation.
--------------------------------------------------------------------------------
The gasoline powered YN27C is an ideal tool for small drilling andbreaking applications or when working at hard to reach sites. Just flip the selector and you have a breaker with a capacity fully compatible with medium sized pneumatic hammers and drills. Pull the start cord and the YN27C will deliver a full hours effective work for just 0.4 gallons of fuel. It will drill a 3 foot hole in hard granite in only three and a half minutes!
Features:
can be used either as a drill or breaker
2 stage fuel system
All metal construction
Washable air filter
Only 4 main moving parts
Vibration reducing handle grips
breaks rock and concrete

Hand-held pneumatic rock drills
For hand held rock drills, we have Y6, Y20, Y19A Y24 and Y26. Among them, the Y6, Y20 and Y24 are widely used in quarrying or construction industry.
Model Y20 and Y24 Hand-held Rock Drill is intended for drilling downward and inclined blast holes in medium hard and herd rock (f=8~18):•The rock drill is mainly used small quarries. Mines for constructing in mountain areas, water conservancy works in capital construction, also for secondary blasting in large mines and other projects.
Air-leg pneumatic rock drills
Our air-leg rock drills have following features:
1. Fit for wet drilling in medium-hard or hard rock
2. Grouped control mechanism, quick to start up, with "air on, water on, air off, water off" machanism, convenient to handle and easy to maintain and repair.
3. Energy-saving and efficient, long service life of parts which are highly interchangeable and reliable performance.
4. YT28 differs from similar products particularly in its high efficiency strong flushing and powerful torque.
