The stud punch head also includes a second arm movably coupled to the head housing and relative to the first arm. The second arm supports a die opposite the punch. The stud punch head also includes a drive mechanism positioned at least partially within the head housing and operatively coupled to a motor of the power tool. The drive mechanism is operable to move the first arm and the second arm toward and away from each other.
