A workpiece holder, measuring device, and a method for executing a measurement by using the workpiece holder. The workpiece holder is configured to hold a workpiece with two opposite arranged workpiece surfaces to be measured in a way that both are accessible by a moveable probe unit and can thus be measured in one setting of the workpiece. For this the workpiece holder comprises a support and a holding body. The holding body has a holding end away from the support with at least one holding surface at which the workpiece is held. In the holding body a free space is formed that adjoins the workpiece surface facing the support when a workpiece is held and makes the workpiece surface accessible for measuring or probing. The accessibility for the probe unit is provided by a transverse channel extending obliquely or orthogonally to the longitudinal axis of the workpiece holder.

The controller is in communication with the first and second motors. The controller is configured to control speed and direction of the first and second motors to effect a desired pattern of axial and rotational movement of the tool. One method includes rotating the first threading in a first rotational direction, and simultaneously, rotating the second threading in a second rotational direction opposite the first direction.
