1. An orthopedic rotary tool, comprising:
a motor;
a drive shaft operatively coupled to the motor;
an output anvil operatively coupled to the drive shaft;
a rotating mass;
a clutch operatively coupled to the rotating mass and the anvil,
wherein the clutch is configured to engage the rotating mass to the output anvil when the output anvil drops to less than a design speed, and
wherein after such engagement the clutch is configured to disengage the rotating mass from the output anvil to allow the rotating mass to reaccelerate; and
a controller configured to:
cause the clutch to selectively couple the rotating mass to the output anvil at a frequency consistent with maintaining an output anvil rpm of less than 500 rpm.
