Hi, all:

I am looking for a small diamond cutting wheel with a cone or inverted
cone shape and a 60 degree edge angle. It should be similar in
appearance to this approx. 3/8" Dremel 7117 wheel:

but I'm looking for one that will fit on a 3/32" mandrel instead of
being mounted on a 3/32" shank like the one in the picture is. This is
so that I can assemble a pair of them together to build a form cutter.

Does anyone:

1) Know the model of a commercially-available wheel that would fit the
bill or

2) Have an opinion on the feasability of taking a few 7117 diamond
cutting wheels to a precision machinist and having them replace the
shaft with a 3/32" hole?

Thanks!
