Abstract
An impact tool includes a housing having a handle portion defining a first axis, a motor supported by the housing and defining a motor axis, and a rotary impact mechanism arranged on a second axis that is perpendicular to the first axis. The rotary impact mechanism is configured to convert a continuous rotational input from the motor to consecutive rotational impacts upon a workpiece. The rotary impact mechanism includes a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer for imparting the consecutive rotational impacts upon the anvil. The hydraulic fluid is configured to attenuate a noise of the rotary impact mechanism that is created by the hammer impacting the anvil. The impact tool further includes a gear train that receives torque from the motor and includes a rotational input that transfers torque to the rotary impact mechanism.
