What is the difference between the bands and the stone on the nail grinder? 

  • The stone can be used for filing nails after clipping or to maintain nails done on a weekly or bi-weekly basis.
  • The course 60 grit band is used for nails that need a lot of length removed. 
  • The fine 100 grit is used similar to the stone.  It takes off a small amount of nail at a time and leaves it with a nice smooth finish.
