1. A driving tool comprising:

  • a flywheel that is rotatable about an axis, the flywheel having an outer rim and a wear-resistant coating that is disposed on an outer periphery of the outer rim, the wear-resistant coating being harder than the outer rim;

    a driver having an engagement surface;

    a roller that is moveable between an unactuated position and an actuated position, wherein positioning of the roller in the actuated position forces the engagement surface of the driver into contact with a rotating edge of the flywheel to thereby transfer energy to the driver such that the driver translates along a driver axis; and

    an electrically-powered actuator for at least partially initiating movement of the roller from the unactuated position to the actuated position.
