About the Product

Files and brushes can't reach under an enhancement, and this bit can. The Under Nail Cleaner Bit is a slim, fine-pointed carbide bit that cleans beneath the free edge and carves a crisp C curve, so every set looks finished from every angle. It's made in the USA for working nail techs and serious hobbyists, with a standard 3/32" shank that fits most professional e-files.

  • Reaches where files can't: the slim, pointed profile gets under the free edge and into tight spaces
  • Crisp C curves: carves a clean, even underside on acrylic and gel
  • Cleaner finish: removes trapped product, debris and natural nail overgrowth
  • Helps reduce lifting: a flush underside means fewer edges for lifting to start
  • Built to last: 150–300 services per bit
  • Made in the USA: premium carbide
  • Fits most e-files: standard 3/32" shank

Why Clean Under the Nail With an E-File Bit?

The underside of an enhancement is the part clients see every time they look at their palms, and it's where product residue and natural nail growth build up. Hand files and brushes can't reach it well. A fine-pointed carbide bit can. It cuts product cleanly with light pressure, so you can detail the underside quickly without digging or overfiling.

What You Can Do With the Under Nail Cleaner Bit

  • Clean up after application. Smooth the underside of gel or acrylic and remove trapped debris before your client leaves.
  • Carve the C curve. Remove natural nail growth under an enhancement for a flush, seamless look and less free-edge lifting.
  • Detail tight areas. Clean and smooth product in hard-to-reach spots to refine the final shape.

  • Acrylic
  • Hard gel and structured gel
  • Gel extensions
  • Natural nails with longer free edges

Frequently Asked Questions

What is an under nail cleaner bit used for?

An under nail cleaner bit is used to clean beneath the free edge of an enhancement and carve the C curve. Nail techs use it to remove trapped product, debris and natural nail overgrowth from the underside of acrylic and gel nails.

How do I carve a C curve with an e-file bit?

After shaping, glide the Under Nail Cleaner Bit gently under the free edge at around 20,000 RPM, following the natural curve of the nail. Remove the natural nail growth under the enhancement with light pressure until the underside is flush and even.

What RPM and direction should I use for the Under Nail Cleaner Bit?

Use medium speed, around 20,000 RPM, in Forward (FWD) direction with light pressure.

How long does the Under Nail Cleaner Bit last?

It lasts about 150–300 services, depending on the product you work with, your speed and pressure, and how you clean and store it.

Does cleaning under the nail help prevent lifting?

It can help. Removing natural nail growth and product buildup from the underside leaves a flush free edge, which gives lifting fewer places to start.

Can I use the Diamond Cone Bit to clean under the nail instead?

Yes, some techs use the Diamond Cone Bit to clean under the nail. The Under Nail Cleaner is a slim carbide bit made specifically for cleaning the underside and carving the C curve, while the Cone is a multi-use diamond bit that also handles shaping and dry manicures.

Will this bit fit my e-file?

Yes, if your e-file takes standard 3/32" bits, which most professional e-files do. That includes the Medicool Pro Power 35k.

Where is the Under Nail Cleaner Bit made?

It's made in the USA from premium carbide.
