Feed roll for power operated trimming tool

A power operated trimming tool comprising:

• an elongated handle assembly including a through bore extending along a longitudinal axis of the handle assembly;
• a drive mechanism;
• a head assembly affixed to the handle extension of the handle assembly, the head assembly including a frame body supporting a feed roll and a blade;
• the feed roll driven about a feed roll axis of rotation by the drive mechanism, the feed roll including:
• a cylindrical core including a first end and a spaced apart second end and an inner surface and a radially spaced apart outer surface, the inner surface defining a central through bore extending along the feed roll axis of rotation, the outer surface of the cylindrical core including a central portion centered between the first and second ends and including a recess bounded by a base and first and second radially extending side walls at opposite ends of the base, a first flanking portion extending between the first end and the central portion and a second flanking portion extending between the second end and central portion;
• and a drive gear formed over the recess of the central portion and integral with the cylindrical core, the drive gear extending along the first and second radially extending side walls of cylindrical recess and protruding radially outwardly, an outer surface of the drive gear driving the feed roll about the feed roll axis of rotation, the first flanking portion including a first plurality of annular sets of drive teeth, each of the first plurality of annular sets of drive teeth including a plurality of circumferentially spaced apart drive teeth, the second flanking portion including a second plurality of annular sets of drive teeth, each of the second plurality of annular sets of drive teeth including a plurality of circumferentially spaced apart drive teeth.
