A cutting blade is secured to a rotating shaft within the inner bore of the handler housing, the cutting blade being aligned with a first portion of the housing cutting profile. A mill is secured to the rotating shaft, the mill aligned with a second portion of the housing cutting profile. An annular mill space is defined by an outer surface of the mill and the inner surface of the inner bore, the annular mill space decreasing in a radial dimension in a downstream direction.
