Notes
  Solid carbide head and shank (.1121" - .1910" tool diameters)
  For best results in reaming tough steel alloys and cast steels, we recommend Type 480 Carbide Tipped Reamer or Type 459 Carbide Tipped Reamer. They utilize special steel cutting grade carbides with excellent cutting and wear characteristics.
