To avoid "rings of fire" when using an electric file, how should the bit be positioned?

Positioning the bit flat on top of the nail is essential to avoid "rings of fire," which are deep grooves or burns that can occur if the bit is improperly angled or used with incorrect pressure. When the bit is held flat against the nail, it evenly distributes the cutting action across the surface, minimizing the risk of heat buildup that can lead to damage. This technique allows for a smoother, more controlled filing process, providing the technician with better accuracy and safety while performing nail enhancements or refinishing natural nails.

The flat position also helps in maintaining the integrity of the nail structure, preventing unnecessary trauma to the surrounding skin and nail bed. Proper bit positioning is key for achieving a polished result without causing discomfort to the client.
