What is the significance of RPM in nail technology?

The correct choice highlights the importance of RPM, or revolutions per minute, in the context of nail technology, particularly regarding electric files or E-files. RPM is a critical measure that indicates how fast the motor of the E-file operates. A higher RPM allows the technician to work more quickly and effectively, especially when performing tasks like shaping and smoothing nail enhancements. It is essential for both efficiency and accuracy, as the speed can influence the effectiveness of removing product without damaging the natural nail or surrounding skin.

In this regard, understanding the RPM of an E-file is crucial for nail technicians to select the appropriate tool settings for various services, ensuring optimal results while maintaining safety during the procedure.
