When shortening acrylic nails with an electric file, the drill bit should be angled at what degree?

• A. 45°
• B. 90°
• C. 75°
• D. 30°

Answer: (B)

When shortening acrylic nails with an electric file, the drill bit should be angled at 90 degrees to achieve the best results. This vertical angle allows the technician to effectively and safely remove material from the nail without causing unnecessary damage to the surrounding skin or the natural nail underneath. A straight approach, as in a 90-degree angle, promotes precision and control, ensuring that the nails are shorted evenly.

Using a different angle, such as 45°, 75°, or 30°, may not provide the same level of control and could lead to uneven shortening or the risk of damaging the nail or cuticle area. Maintaining the vertical position of the drill bit is key for both efficiency and safety during the filing process.
