The pneumatic hammer is a portable drill that is powered by compressed air. It was once considered a state of the art drill in the U.S. However, pneumatic hammers are only being used by a small portion of people today. During the roadwork, the pneumatic hammer is used to break up road surface.
Break Asphalt and Macadam Pavements
One of the common uses of the pneumatic hammer is to cut out asphalt and macadam pavements for the railway tracks or sinking of pipelines. The process of breaking the asphalt street is very strenuous as it involves a lot of work. However, the pneumatic hammer can cut the asphalt in sharp and definite form. During the cutting, two chalk lines will be marked on the surface so that the pneumatic hammer can follow the lines and cut through the asphalt.
Drilling Concrete Walls
A pneumatic hammer can be used to drill against walls and steep slopes. In order to overcome the gravity problem, it will require two men to provide the horizontal force to drive the tool against the wall.
Breaking Metal and Rocks
A light, hand held pneumatic hammer is used for breaking the paint from metal and rock into small fragments. A large pneumatic hammer can be fitted to the mechanical excavators or rear tractors for use in mining and quarrying.
Drilling Holes on Stone Work
The pneumatic hammer is suitable for drilling holes in stone work on a building and can be used to drill holes in a concrete wall to pin concrete footings. Sometimes, it is also used to drill holes in the floors to pin the wall framing. During the drilling process, the hammer will loosen up the masonry.
Break Concrete in a Faster Speed
The pneumatic hammer can spin a drill bit as well as punching in and out along the axis. The actual in and out drilling distance and the force of the blow is small. The hammer can move at thousands of BPM (Blows per Minute). Although each blow uses low force, the fast spinning speed of the drill bit allows it to loosen the concrete and brick. Thus, a pneumatic hammer is faster in drilling concrete compared with a standard drill.
Standard Drill for Wood or Metal Work
A pneumatic hammer has a lever that secures the hammer clutch so that it can be used as a standard drill for wood or metal surfaces. Although a hammer drill is expensive, it is more preferable to use for drilling concrete work. For example, the pneumatic hammer can attach items to the wood studs when used as a conventional power drill. If it is used as a hammer drill, it can be used to attach items on the masonry walls.
There are several benefits in using pneumatic hammers. Pneumatic hammers can be mounted on light carriers because of the neutralization of the extra hydraulic demands by the air compressor. Mounting an air hammer will only require some mechanical changes. The high weight to power ratio allows pneumatic hammers to operate better in confined spaces compared with hydraulic hammers.
