A cutting tool holder (1) for holding and driving a cutting tool (2) includes at least one actuator (3) for adjusting at least one operating state of the cutting tool holder (1). A control module (4) is disposed on the cutting tool holder (1) and is connected with the actuator (3). The control module (4) directly and independently actuates the actuator (3); information about the operating state is storable on the control module (4). A TCP- and/or UDP-based server is disposed on the control module (4) so that information transmitted from a web-browser compatible end device (5, 6) about an operating state to be assumed can be received and information about the actual operating state can be transmitted to the web-browser compatible end device (5, 6).
