The dental hand tool is arranged with a handle comprising at least a connector and a coupling member at one end thereof. The dental hand tool is in particular provided with a second connector and a second coupling member at the other end of the handle. A modeling tip (30) is provided that comprises a shaft and that is suitable for the coupling member. The modeling tip comprises a coating of a material that is more flexible compared to the remaining material of the modeling tip. In particular, the material has a smaller surface energy compared to the remaining material of the modeling tip.
