An integrated surgical tool system (30) for energizing different powered surgical handpieces (32, 33). Internal to each handpiece is a non-volatile memory (72) which stores data regarding the operating parameters of the handpiece. This data, includes information about the speeds at which any motor internal to the handpiece should be driven, the maximum current that should be drawn by the handpiece and the maximum internal temperature of the handpiece. The handpiece is plugged into a complementary control console (36). The control console reads the data in the internal memory. Based on the retrieved data and manual control signals, the control console supplies energization signals to the handpiece so as to cause the appropriate actuation of the handpiece.
