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.

10. An 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 (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
