I have some like that that I got many years ago from my dentist. At least the peculiarly-shaped end looks the same and is what caught my eye in your photo. When I got mine they were already a little rusty (compared to a lot of smaller ones I got from the same guy) so it made me suspect they were maybe for an old-style hand piece that wasn’t used much anymore. I still use the smaller burrs I got from him for hand engraving and micro-routing, but the larger ones I never have used — the shank is a weird size at about 0.090” so none of my Dremel collets fit.Anybody have an idea what all these little cutters would be for?
