E-File, Explained
Quick definition
The electric drill that removes product and cleans cuticle zones with interchangeable bits.
Modern e-files spin ceramic or carbide bits at adjustable speeds: coarse bits take down acrylic length, fine safety bits clean around the eponychium without cutting skin.
Speed discipline is everything — high RPMs on natural nail or thin bits near skin cause permanent damage; this is the tool that separates trained techs from YouTube graduates.
