A Guide to Choosing the Right Flame Bit for Cuticle Work

If you’re diving into e-file manicures and have seen russian manicures on social media, you’ve probably come across flame bits, those sleek, tapered bits that are staples for detailed cuticle work. But with so many options in size, grit, and coating, it can get confusing.

Do you need a fine or medium flame? Large or narrow?

Let’s break down what flame bits are, how they’re used, and how to choose the right one for your technique and client needs.

What Is a Flame Bit?

A flame bit is a tapered, pointed e-file bit designed primarily for cuticle and sidewall work. Its slim shape allows for precision when lifting, exfoliating, or cleaning around the proximal nail fold and lateral walls.

They’re most commonly made from diamond material and come in different:

• Sizes (micro to large)

• Grits (extra-fine to medium)

The Mai Bit (fine grit, micro size)

The Cuticle Lift Bit (large size, fine grit)

Cuticle Pro Lift Bit (medium grit, micro size)

What’s the Flame Bit Used For?

Flame bits are used in dry manicure techniques to:

• Gently lift and exfoliate dead skin from the nail plate

• Clean the cuticle area

• Refine and smooth the nail fold

• Prepare the nail for enhancements or gel polish

They’re excellent for getting into small, tight spaces when used with training and care.

 Key Differences Between Flame Bits

Here’s a breakdown of the key variations in flame bits and how they affect your work:

  1. Size

Size

Best For

Mini flame (1.6–1.8mm)

Small nail, intricate detailing, nervous techs

Medium flame (2.1–2.3mm)

Everyday use, standard nail sizes

Large flame (2.5mm+)

Quick work, wide nails, thicker cuticles


The smaller the bit, the more precise, but the slower it is to work with. Larger flames cover more surface but require more control.

2. Grit

Grit

Use

Extra-fine

Sensitive clients, soft skin, light exfoliation

Fine

General cuticle cleaning and prep

Medium

Thicker cuticle, coarser skin, faster exfoliation

Coarse

Rarely recommended near live tissue, use with caution or for callus work only


Start with fine grit for general work and only use medium on thicker buildup. Never use coarse grit near the proximal fold unless it’s for hard skin areas and even then, very carefully.

3. Material and coating 

Type

Benefits

Diamond

Standard for cuticle work, long-lasting

Carbide Steel

For removal of product, never for prep

Ceramic

Good for nervous techs, poor results


Diamond coated flame bits like the Katie Barnes Cuticle Lift Bit or Pro Lift Medium Flame Bit are preferred for their glide and reduced heat, helping prevent discomfort for clients.

Safety Tips

  • Never use a flame bit without proper training as incorrect angles or pressure can cause damage.
  • Use at low speed (typically 5,000–10,000 RPM) for control.
  • Avoid over-exfoliating - you’re removing non-living tissue only.
  • Never dig in, let the bit do the work for you
  • Don't use a flame bit as a pusher - it is to lift only
  • Always disinfect or sterilise your bits between clients.
  • Match flame bit size to the client’s nail anatomy for comfort and precision
