This antique Kerr Electro-torque Dental Drill is a must-have for collectors of medical equipment. It's a rare piece from the early 20th century and would make a great addition to any collection. This drill was used in the field of dentistry and helped dentists perform procedures on patients with precision and accuracy. The design of the drill is unique and showcases the innovation of the time. It's a great conversation piece and would be perfect for display in a museum or personal collection.

I cannot attest to the usability of the item, as I have not tested it. I am selling it as-is, I have no idea if it works.
