I bought a nail drill to aid me in filing the top coat off my nails. It has been hard on my back as I've bent over my toenails dragging my nail file back and forth across the tops of my toenails. The nail drill really helps a lot! It's also really precise.
In the video below, I show how the nail drill works and what attachment I used. I'm a not a licensed professional nail tech, so all this information is to be taken with a grain of salt and only as reference. This is NOT an instructional video.
