An e-file (electric nail file) is a professional tool used in the nail industry to shape, smooth, and remove product from the natural nail or enhancements more efficiently. It’s a handheld machine with interchangeable bits that spin at adjustable speeds, allowing for precise and controlled work. Nail techs use an e-file because it saves time, creates a cleaner and smoother finish, and reduces strain on the hands compared to traditional filing. When used correctly, it helps achieve professional, flawless results while maintaining the health of the natural nail.
