Choosing the right cuticle bit for e-file prep
Choosing the right cuticle prep bit can feel overwhelming with flame bits, ball bits, cone bits, diamond grit, titanium coating… where do you even start?
Whether you’re new to e-filing or refining your prep routine, selecting the correct bit for your client and technique is essential for:
• Safe exfoliation
• Long-lasting enhancements
• A smooth, professional finish
Let’s break down the most important factors to consider and how the Katie Barnes E-File Bit range makes it simple.
First: What Does a Cuticle Prep Bit Actually Do?
Cuticle prep bits are designed to:
• Lift the cuticle from the nail plate
• Exfoliate non-living tissue (cuticle)
• Clean the lateral folds (sidewalls)
• Remove dead skin and debris
• Create a clean canvas for product adhesion
A common mistake? Using the wrong bit or angle and damaging the skin or nail. Choosing the correct bit type, size, and grit is key.
Consider These 3 Things When Choosing a Bit:
1. Client’s Nail Anatomy & Skin Type
• Small nails? Use Extra Small Tapered Erin or mini flame such as The Mai or Pro Lift Small or small ball bits
• Dry, compact cuticle? You might benefit from a medium grit flame such as Pro Lift Medium or KB Erin Bit in medium grit
• Delicate, sensitive skin? Stick to fine grit in KB Tapered Erin, low speed
Your Technique & Experience Level
• Are you confident with detailed prep work?
• Do you use a single bit or a multi-step cuticle routine?
• Are you working dry, or combining with manual tools?
Beginners might prefer gentler bits like the Katie Barnes Fine Tapered Erin Bit or The Mai.
Advanced techs may layer bits - starting with a flame to lift, finishing with a ball or skin polishing bit to exfoliate after application.

• Soft, lifted cuticles for clean polish line? → Mini Teardrop Bit - KB Tiny Lift Bit
• Exfoliated skin and tidy folds? → Fine Ball Bit or Lucy Bit
• Deep clean for enhancement prep? → Medium Grit Flame or The Erin Bit medium grit
