Method for determining a working depth of a tool and tool for machining a workpiece

Method for determining a working depth of a tool, comprising

• a) arranging a tool and a depth determination device on a depth setting device in such a way that
• a mounting device of the depth determination device is located at least partially around a clamping region of a shaft of the tool such that the depth determination device is free to move relative to the tool in an axial direction, and
• a stop surface of the depth determination device (5) lies against a contact surface of the depth setting device, and a cutting edge of the tool lies against a limit stop (49) of the depth setting device;
• b0) applying a predetermined compression force in axial direction to the depth determination device, such that at least a part of the depth determination device is elastically compressed by a certain compression amount against the contact surface, obtaining a compressed state of the depth determination device;
• b) securing the mounting device to the clamping region of the shaft in the compressed state of the depth determination device such that the mounting device is firmly mounted to the clamping region of the shaft, whereby a tool assembly is formed;
• c0) releasing the compression force from the depth determination device, and
• c) removing the tool assembly from the depth setting device.
