[origin: EP2405098A2] The arrangement (100) has a chisel holder (10) fastened or fixed to a milling drum. A milling bit (20) is secured in a hole of the holder, and rotates around a longitudinal axis. An anti-swiveling wear plate (30) is arranged between a stop surface of the holder and a milling bit head (21) of the bit. An anti-twist plate is arranged between the wear plate and the holder through a groove (31) formed in an external periphery of the wear plate. An intervening guide channel (11) formed at the holder is inserted into the groove. The wear plate is made of a spring steel material.
