What is this tool?

[barcuna]

Good morning all. Can anyone help ID this tool? It has a MT#3 taper.

Thanks in advance.

Looks like a slitting saw arbor .

Use it with a draw bar or key to keep it locked in place

Are those four removable spacers behind the nut?
It could also be used on a horizontal mill for holding cutters, although it does look short....perhaps for a smaller machine.
Note too the centre in the outboard end for extra support.
Below is a picture from "the net".

I'm not sure if they are separate spacers or one piece, They are held by a square key. I'm going to try and remove it (or them) and I'll let you know what I discover.

Slitting saw arbor . The spacers are separate for different thicknesses of the cutters .
