ABSTRACT:
A cutter tooth holder assembly is adapted for attaching a cutter tooth having a plurality of spaced cutting tips to a rotatable cutter drum. The tooth holder assembly includes a base for being mounted to an outer peripheral surface of the cutter drum. The base has a tooth-locking, circumferentially-extending groove formed in its top surface. A tooth holder is positioned in the tooth-locking groove, and has a front bearing surface residing adjacent a back end of the cutter tooth. The cutter tooth is arranged such that one of the cutting tips resides in the tooth-locking groove to prevent rotational movement of the cutter tooth during operation of the cutter drum, while an opposed second one of the cutting tips resides in a cutting position relative to the outer surface of the drum. An elongate, threaded bolt cooperates with the tooth holder for attaching the cutter tooth to the tooth holder assembly.
