What type of electric bit has razor-like edges known as flutes?

• A. Carbide
• B. Diamond
• C. Steel
• D. Ceramic

Answer: (A)

The type of electric bit that has razor-like edges known as flutes is carbide. These fluted edges are designed to efficiently remove material from the nail surface, allowing for precision and speed during nail treatments. Carbide bits are particularly favored in nail technology for their durability and effectiveness in grinding down hard materials, such as calluses or thickened nails.

Carbide bits can create a smoother finish compared to other materials, making them ideal for both professional and DIY nail care applications. Their sharp flutes allow for a clean cut and minimal risk of chipping or damaging the surrounding nail area. This characteristic makes carbide bits a staple choice in a nail technician's toolkit, especially when looking for performance and longevity in tools.
