There are two pilot bits(one was used twice), and new cutters for 3/4", 1" and 1-1/4" taps though the 1-1/8" cutter for the 1-1/4 tap is a Milwaukee Hole Hawg and not a Wheeler Rex cutter. It all comes in it's own case.
You can get adapters for other size taps and threads. There is a video on how to use the tool here.It was too expensive to hire someone else to do the taps in the rural location it was.
