Abstract
According to one implementation, a tool driving device includes a drill chuck, a motor, a casing and a vibrating mechanism. The drill chuck holds a drill. The motor is configured to rotate the drill chuck. The casing houses the motor. The vibrating mechanism is configured to periodically reciprocate the drill chuck relatively to the casing in a tool axis direction during rotation of the drill chuck. The vibrating mechanism is configured to distance the drill chuck from the casing at a first speed smaller than a second speed for bringing the drill chuck close to the casing.
