TOOL DEVICE AND METHOD

The invention relates to a tool device (10) having a drivable tool (1)， comprising a shaft (2) coupled to the tool (1)， also comprising one or more braking elements (3) that are arranged in a manner distributed in particular in the circumferential direction (4) about the shaft， wherein the tool device (10) is configured， as part of a braking operation， to move the one or more braking elements (3) from a released state into a braking state， wherein， in the braking state， the one or more braking elements (3) are in contact with the shaft and as a result exert a braking force on the shaft (2) such that the shaft (2) and as a result also the tool (1) are braked， and wherein， in the released state， the one or more braking elements (3) are not in contact with the shaft (2).

本发明涉及一种带有可驱动工具（1）的工具装置（10），其包括与该工具（1）传动连接的轴（2），还包含一个或多个制动元件（3），所述制动元件尤其沿环绕该轴的圆周方向（4）分布布置。该工具装置（10）被配置为：在制动操作过程中，将一个或多个制动元件（3）从释放状态切换至制动状态；在制动状态下，一个或多个制动元件（3）与轴（2）接触，并由此对轴（2）施加制动力，使得轴（2）进而带动工具（1）一同被制动；而在释放状态下，一个或多个制动元件（3）不与轴（2）接触。
