Well, someone showed me that there are also small, handheld, rechargeable "ultrasonic scalers" available for around $20. Could they also be made to work? I decided to purchase one to find out. It arrived today. The answer is no.

These tools may be advertised by sellers as "ultrasonic scalers" but they do not contain a transducer. In fact, the product packaging and manual themselves make no claims of being ultrasonic. It's just a vibe motor -- much like the one that vibrates your phone, or a cheap electric toothbrush. And that's all it is. A handheld vibe motor with a dental scaling tip on it.
I burned the $20 so you don't have to! eBay uses the magic word "ultrasonic" in the name and description of these tools but they are not. Maybe I can make a micro sanding tool out of it or something, but I won't be making an ultrasonic cutter out of it, that's for sure.
