These pneumatic tools are in a sense the smallest of the jackhammer family. The one here has a small point bit and could be used one handed if necessary.
This larger tool is mostly used with two hands, one on the trigger and the other holding the end of the barrel. Heavy gloves would be worn of course.
These are typically stone mason's tools used mostly in permanent workshops. They use the basic moil point and various chisel points depending on the job.
Rotary hammer drills are everywhere on building sites and for good reason. There are quite powerful and do a good job drilling larger sized holes in concrete and masonry. However that's not all...
A very useful function of most large hammer drills is the ability to stop the rotation and with the aid of a chisel tool use it for chipping or scabbling cement and concrete. This particular tool in it's 25 years working life probably spent 60% of it's time chipping. It is excellent for chasing masonry walls, scabbling small areas of concrete in preparation for ceramic tiles etc. etc.
Note the tool above is branded by the Australian company Ramset, but it is in fact a version of the German Bosch tool.
One of the reasons that these tools last so long is that when you see this configuration with a large lump hanging lower that the output drive, it means that there is a significant gearbox in there and in most cases they are running in an oil bath.
The electrics suck up dust of course and the best thing to do is to always keep the airways clean and never place gloved hands over the inlets as this can cause overheating.
