This bit is nice to use for when preparing the cuticles and the natural nails. You can easily roughen the natural nails with this bit. Use this bit with 9,000 - 15,000 rpm.
The grit of the bit is blue, so a medium grit, use for rougher skin (sidewalls with calluses) and cuticles. This bit makes it easy to remove calluses along the cuticles and fingertip.
Disinfect the bits thoroughly after each use. This can be done in an ultrasonic or in barbicide (both available from us).
