A system for controlling operation of a power tool. The system includes a handpiece having a power tool, a radio frequency identification (RFID) tag, and a wireless transceiver. The system also includes a power pack having an electric motor driving the power tool. The power pack also includes a wireless transceiver, an RFID reader, and non-transitory computer-readable storage media having computer-executable instructions for pairing the handpiece to the power pack. When executed by at least one processor, the computer-executable instructions cause the at least one processor to: interrogate the RFID tag with the RFID reader; receive an RFID signal from the RFID tag including identifying information for the handpiece; store the unique identifying information for the handpiece at the power pack; and, based on receipt of the unique identifying information, complete wireless pairing of the handpiece to the power pack.
