You can use the BOSCH Rotary Hammer to chisel off plaster, run cable channels or remove tiles. To do so, be sure to disable the rotary movement. You only need that for drilling. Some hammers have to be fitted with an additional chisel attachment for chiselling.

There are different chisel shapes for different materials and purposes. For example flat or spade chisels for removing tiles and gouging chisels for running cable channels.
