Wall chasers are tools that quickly cut chases in walls. Usually these tools are powered by electric motors and generally are equipped with two blades that are located on a shaft. Usually this tool is used for making space in walls for things like cables and pipes. This way it is possible to bury and hide them out of view. In the past the user had to do this job with the help of a hammer and a chisel. This technique still is doable in small jobs and on not very hard materials like plaster , but on hard materials it is too slow , demanding and very difficult to manage. A good thing about using wall chasers is that they have a port that for attaching a dust extractor. This way the user have a clean and healthy jobsite. Some models are also equipped with Laser cutting Line Indicator.
