Abstract
A rotary hammer includes a housing and a tool receptacle extending from a first end of the housing. A dust box is coupled to the housing and a motor is positioned within the housing. The motor defines a motor axis. A drive assembly is rotated by the motor about a working axis. The drive assembly is arranged relative to the motor so that the motor axis is at an oblique angle relative to the working axis.
