Abstract (en)
The device (100) has a holder (130) with a recess and a chisel (160) with a shaft (168) held by the holder, whereby the chisel is rotatable about the longitudinal axis of the chisel shaft and is held in the chisel holder with the aid of magnetic force. The chisel is essentially held in the holder by a holding force acting along the chisel shaft and caused only by magnetic force. An independent claim is also included for a method of holding a bit for a cutter with a rotatable cutter roller.
