A Low-Speed Dental Handpiece Set refers to a collection of dental instruments designed to operate at slower rotational speeds, typically between 2,000 to 40,000 RPM. These handpieces are powered by either electric motors or air-driven motors, and they are essential for tasks requiring precision, control, and torque rather than speed. They are used in various dental procedures, such as polishing, finishing restorations, cleaning teeth, root canal treatments, and prosthetic work.
