ABSTRACT:
A cutter drum of the type adapted for use in milling a roadway surface is disclosed, and which comprises a plurality of flighting assemblies fixed to the surface of the drum in a helical configuration. Each flighting assembly comprises a base plate which is aligned with a plane which perpendicularly intersects the central axis of the drum, and rear and forward support blocks fixed to one side of the base plate to define a channel therebetween. 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.
