Nail files, buffers, and polishers are required in almost all nail sculpting and nail decorating tasks, so it’s evidently a must to stack up all the essential equipment you need to shorten and shape natural nails, to prepare the nail surface for gel polishes, acrylics, or gel, to file the smile line, to shape and refine the nail surface, or to buff the nails for a lustrous shine.
What do the “grit numbers” of nail files, buffers, and polishers mean?
Grit numbers show how coarse a nail file, buffer, or polisher is. Grit numbers are determined according to the amount of grit the given tool contains per square inch. What this means is that nail files, buffers, and polishers with high grit numbers are coarse, while products with low grit numbers are gentle. The below table demonstrates the most widely-accepted categorization of nail files, while also determining the tasks each file type is designed for.
|File Type||Grit Number||Use|
|Extra coarse files||60 - 80||Filing gel and acrylic nails,
reducing length or surface
|Coarse files||100 - 150||Shaping gel and acrylic nails,
|Medium files||150 - 240||Shaping, preparing, smoothing
all types of nails
|Fine files||240 - 400||Surface work on natural and
artificial nails, shaping the free
edge (natural nails)
|Extra fine files||400 - 900||Preparing the nail surface for
shining and buffing
|Ultra-fine buffers||900 - 12,000||Smoothing / buffing natural
and artificial nails
