NIC Nail Technician Written ExamNail Technology ProceduresHard
A technician is performing a dry manicure using an electric file (e-file). After gently pushing back the cuticles with a rubber bit, the technician needs to carefully remove excess non-living tissue from the nail plate and around the cuticle area without damaging the eponychium or nail plate. Which e-file bit shape is most appropriate for this precise and delicate task?
- AMandrel with Sanding Band
- BLarge Barrel Bit
- CPedicure Flat Top Barrel Bit
- DTapered Cone Bit (or 'Flame' bit)
Show answer & explanationAnswer & explanation
Correct answer: D. Tapered Cone Bit (or 'Flame' bit)
A tapered cone bit, often called a 'flame' bit, is ideal for delicate cuticle work and removing non-living tissue from around the eponychium and sidewalls due to its slender, pointed shape and fine grit, allowing for precision without damaging the surrounding skin or nail plate.
Why the other options are wrong
- A. A mandrel with a sanding band is used for aggressive filing, reducing length, or preparing enhancements, far too harsh for cuticle work.
- B. A large barrel bit is used for reducing bulk or shaping enhancements, not for delicate cuticle work.
- C. A pedicure flat top barrel bit is designed for reducing calluses and rough skin on the feet, not for delicate manicure cuticle work.

Memory trick: For Fine Flame-like features, choose the Flame bit.
