Good to know
Choosing a bit is two questions: which area of each nail, and how much product to remove. Barrels work the surface, cones and needles reach the cuticle area. Drill bits do the heavy lifting in modern prep and removal. Shape decides where a bit works (surface, sidewalls or cuticle area) and grit decides how fast it removes.

Why it works
