1. A torque-limiting device comprising:
a body comprising a handle that is configured to be grasped by a user;
a motor positioned in the body;
a drive head operatively connected with the motor and configured to drive a drilling implement; and
a processor positioned in the body;
wherein, under the control of the processor, the torque-limiting device is configured to:
detect a first torque value when the drilling implement is drilling in a first type of body tissue;
detect a second torque value when the drilling implement is drilling in a second type of body tissue;
detect a change between the first and second torque values that is indicative of the drilling implement passing from the first type of body tissue into the second type of body tissue, said change comprising an increase or decrease in torque; and
stop the drilling of the drilling implement based on detecting said change.
