A method is provided for testing the fit or for testing the imbalance of a tool exchangeably accommodated in a tool spindle which is mounted for rotation about a central longitudinal axis and is rotationally driven by a spindle drive motor, including: inserting the tool on the tool spindle; making the tool spindle rotate with a specific rotational frequency fdef about the central longitudinal axis by means of the spindle drive motor; analyzing an actual value of a controlled drive current of the spindle drive motor with respect to a frequency component with the rotational frequency fdef; and determining whether the frequency component with the rotational frequency fdef lies within a threshold value range.
