When using a nail drill, how should the angle be positioned relative to the nail bed?

When using a nail drill, positioning it flat against the nail bed is crucial for several reasons. This angle allows for even distribution of pressure across the nail's surface, which helps prevent any unnecessary damage or trauma to the nail bed and surrounding skin. A flat position also aids in ensuring that the drill can efficiently file or shape the nail without causing uneven surfaces or ridges.

Using an upright or tilted angle may lead to uneven filing and could increase the risk of harming the cuticle or nail bed. Similarly, a diagonal or curved position can create difficulties in achieving a uniform finish, as these angles can lead to an uneven application of pressure and result in an awkward nail shape. Therefore, maintaining a flat angle is the safest and most effective approach when operating a nail drill.
