The housing defines a barrel portion, a handle portion opposite the barrel portion, and a motor housing portion between the barrel portion and the handle portion. The percussion tool also includes an electric motor positioned within the motor housing portion and a percussion mechanism driven by the motor and including a striker supported for reciprocation in the housing. The striker defines a striker axis in a reciprocating direction.
