Wall chaser is used for preparing grooves on the interior walls for installation of in-wall electrical sockets, conduits, water pipes, etc. Experimental results reveal that the application of a wall chaser achieves a significant structure-born noise reduction of around 19dB(A) as compared with that of using a traditional percussive hand-held breaker. In the use of removing wall plaster, a wall chaser can be alternately used with a breaker, which can largely reduce the time of operating the breaker.
