I picked this up in the estate sale items this past weekend. It is used by electricians to tap or chase threads in electrical cabinets according to what I found on the web.
Good find. Never saw a Craftsman.
My electrician brother-in-law always called them triple taps. His were Kleins. They had replaceable shafts.
