A method for cutting with a tool comprises rotating the tool in a first direction. Then, at a predetermined moment, quit rotating the tool and allow the tool to coast in the first direction. While the tool coasts, a parameter is determined that represents drag experienced by the tool as the tool coasts. If the determined parameter does not exceed a predetermined limit then the tool is rotated in the first direction. If the determined parameter exceeds the predetermined limit, then the tool is rotated in another direction opposite the first direction. The predetermined moment when the tool begins to coast may be any desired moment, such as when the tool rotates through a specific distance or for a specific period of time.

An apparatus for controlling asymmetrical coasting of an endodontic reciprocating motor includes a controller operatively connected to the endodontic motor. The controller may include a processing unit that is configured to direct the rotation of the endodontic motor in the forward direction for a coast time and configured to direct the rotation of the endodontic motor in the reverse direction for a coast time. The forward coast time is separately calculated from the reverse coast time. A method for asymmetrically coasting a reciprocating endodontic motor includes rotating an endodontic motor in a forward direction and calculating a forward coast time for the forward direction and coasting the endodontic motor in the forward direction for the calculated forward coast time. After coasting the endodontic motor in the forward direction, the endodontic motor is rotated in a reverse direction. The reverse coast time is different than the forward coast time.
