1. A hand-held drill, comprising:
- a motor;
a chuck selectively rotatable by the motor;
a body adapted to support the chuck and the motor in an operative position relative to each other, wherein the body includes a handle adapted to be gripped by a user to operate the drill; and
a motor control including a trigger configured to be selectively depressed through a range of positions by a user, wherein the range of positions includes an initial position, in which the trigger is not depressed, and a final position, in which the trigger is fully depressed, and further wherein the motor control, in at least one configuration, is adapted to cause the chuck to rotate by a predetermined finite number of revolutions dependent at least in part upon the position to which the trigger is depressed within the range of positions.

8. A hand-held drill, comprising:
-
a chuck;
a motor configured to rotate the chuck;
a power source adapted to deliver power to the motor;
a housing within which the motor is positioned and from which at least a portion of the chuck extends, wherein the housing includes a front portion from which at least a portion of the chuck extends, a rear portion that is generally opposed to and spaced-apart from the front portion, and an edge region extending between the front and the rear portions and defining at least a portion of a contact surface, wherein the housing is sized to be held in a user'"'"'s palm, with the rear portion generally facing the user'"'"'s palm and a user'"'"'s fingers gripping the contact surface, wherein the housing has a first dimension measured between the front and the rear portions generally parallel to a long axis of the chuck, and a second dimension measured in a direction transverse to the long axis of the chuck between opposed portions of the edge region, and further wherein the first dimension is less than the second dimension. - View Dependent Claims (9, 10, 11, 12)

13. A electrically powered hand drill/driver, comprising:
-
a chuck;
a motor configured to rotate the chuck;
a power source adapted to deliver power to the motor;
a selectively actuable user input; and
a controller electrically connected to the power source and the motor and configured to regulate rotation of the chuck by controlling the delivery of power to the motor from the power source, wherein the controller is configured to receive a signal when the user input is actuated, and upon receipt of the signal from the user input, the controller causes the chuck to rotate by a predetermined increment. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
