A tooth holder is mounted in the channel, and the holder has an outer portion which extends radially above the outer edge of the base plate, and the tooth holder is releasably mounted in the channel by means of a bolt. The portion of the tooth holder in the channel is protectively covered by the side surface of the base plate of an adjacent assembly.
