I just call for the round blade

1-2 inches diameter
Try sear or home improvement store


Rockler carries something approaching this for press-in barbed jewelry box hinges.

If 2" is too big, look for a Dremel saw blade (circular saw attachment)
Answers:    A company called Micro-Mark sell miniature saw blades like that, from 3/4" to 2" contained by diameter. But check to see if your mandrel will fit.

I've purchased things from them in days gone by. They have some pretty appropriate hobby tools.
