Abstract

A hammer drill in which modes of a tool bit can be changed between each other in a reasonable manner. The hammer drill has signal output sections provided corresponding to the modes and outputting an electric mode signal corresponding to a mode selected from among the modes by manual operation by a worker; a control section for outputting electric drive signals corresponding to mode signals inputted from the signal output sections; and a mode change operation section (169) operating in response to a drive signal from the control section and changing a mode. The mode change operation section (169) has a mode change motor (174) driven by a drive signal from the control section and also has mode change sections (172, 173) operated by the mode change motor (174) and changing the modes between each other.
