Claim 12:
13. A powered ratcheting wrench comprising:
a main housing defining a grip portion;
a motor having a motor drive shaft rotatable about a first axis;
a drive assembly coupled to the motor drive shaft and driven by the motor, and an output assembly coupled to the drive assembly, wherein the output assembly includes a ratcheting mechanism and an output member, both of which receive torque from the drive assembly, causing the output member to rotate about a second axis that is perpendicular to the first axis;
a head housing coupled to the main housing and surrounding at least a portion of the drive assembly and at least a portion of the motor, wherein the head housing defines a first end of the wrench and the main housing defines an opposite, second end of the wrench; and
a battery pack selectively coupled to the main housing at the second end for providing power to the motor when activated,
wherein the head housing is composed of an A380 aluminum alloy resulting in a center of gravity of the wrench that is enveloped by the hand of a user when being grasped by a user,
wherein the center of gravity is between 170 millimeters and 185 millimeters away from the first end when the battery pack is coupled to the main housing.
