Dear Ms. Allyson Morrison, If you are planning to engrave glass, I
strongly recommend using a high-speed air driven dental handpiece
which can deliver speeds up to 400,000 rpm.
The dental type handpiece is much more comfortable and easier to use
than a dremel or the typical flex shaft unit. These type of units
have a tendency to vibrate somewhat, as opposed to a dental
air-driven handpiece which works on air, (no vibrating motor) to
interfere with the delicate carving that you want to do.
If you should have any further questions that I may be able to help
you with, please feel free to contact me directly at:
Sincerely, Richard Lucas…
