A handheld micro motor has what key feature?

1. Multiple attachments

2. A built-in light

3. Greater torque

4. A specific speed setting

The correct answer is: Greater torque

A handheld micro motor is specifically designed for nail technology and one of its key features is greater torque. Torque refers to the rotational force the motor can provide, which is essential in nail services where precise and powerful handling is necessary, such as during filing, shaping, or cutting. The ability to maintain higher torque allows technicians to perform these functions more efficiently and effectively, especially when working with different types of nails and products. This feature enhances the overall performance of the tool, making it a preferred choice among professionals in nail care. While multiple attachments, built-in lights, and specific speed settings can be useful features of various nail tools, they do not define the primary advantage of a handheld micro motor. These additional features can improve usability and convenience but the standout characteristic that distinguishes micro motors in a professional setting is their increased torque, which directly impacts the quality of work performed.
