First....I love these!!!!  I am not a professional.  I just wanted to do my nails well.  So after using the bits that came with my drill.  I decided to try these as the many videos that I watched were using them.  The make a very big difference.  My nail removal and prep time are more than cut in half.  These bits are GREAT.  I intend to replace all my bits with these.  The ones that came with the drill are now put away.  I cannot say enough how much I love these bits.  You should definitely purchase these. You will not regret it.
