[origin: WO9900580A1] The invention relates to a chisel arrangement for the cutting chisels of a tool holder mounted in a rotating manner, such as a cutter head or cutting rollers, in which the chisel tips are inclined in a leading manner in the direction of rotation and the direction of circumference of the tool holder and the chisel can be tilted by overcoming a spring force. The tilt axis of the chisel (1) is positioned on the tool holder (7) in the direction of the circumference and rotation of the chisel (1) in front of the projection of the chisel tip towards the axis of rotation (9) of the tool holder (7). In the contact position, the chisel (1) is supported against a spring (3) in a tiltable manner.
