Abstract: A power tool/battery pack combination includes an electric motor, one or more electrochemical cells, and a capacitive element. The electric motor is connected in series to a first switch. The series combination of the electric motor and the first switch is connected to a first terminal and a second terminal. The one or more electrochemical cells are connected across a third terminal and a fourth terminal. The third terminal and the fourth terminal are coupled respectively to the first terminal and the second terminal. The one or more electrochemical cells supply power to the electric motor via the first switch. The capacitive element includes one or more capacitors. The capacitive element is connected across the third terminal and the fourth terminal. The capacitive element is capable of storing inductive energy generated by the one or more electrochemical cells.

Abstract: An adaptor for connecting a power source to a power tool includes a housing having a first end that is configured to connect to a power source and a second end that is configured to connect to a power tool. The adaptor includes a control circuit disposed within the housing. The control circuit is configured to detect a type of the power tool, to detect an overstress condition in the power tool and to control the power tool responsive to detecting the overstress condition based on the detected type of power tool.

Abstract: A power tool for drilling a hole in a workpiece made of wood or a wood material. The power tool generally includes a tool housing defining a handle and a motor contained within the tool housing that includes an output shaft that spins about a motor axis. A gear housing is connected to the tool housing. An output spindle is supported for rotation about a spindle axis in the gear housing. The spindle axis is disposed about ninety degrees from the motor axis. A gear portion on the output shaft is engaged to a gear portion on the output spindle. The motor and the gear portions are configured to rotate the output spindle at a speed in range from about five thousand revolutions per minute to about twenty-five thousand revolutions per minute. A cutting member is connected to the output spindle. The cutting member includes fluted cutting blades. A carriage assembly includes a base member and a head member connected by a first post having a first compliant member and a second post.
