Thanks! (Bookmarking THAT page.) Hmm. I don't see a price.

It looks as though they have online sales, but I can't get the
price information, even after adding one to the shopping cart. (Nor can
I see any other information about the item.) Perhaps it insists on only
talking to Microsoft's "Internet Explorer". :-)

There's another problem. It is designed to fit into 5C collets
or 16C collets -- with a bore of 1". I don't think that there is one of
that size available for your machine, as a 5C collet needs at least a
1-3/8" spindle through hole for the collet drawbar.

Good Luck,
DoN.
