Mandrel nail bits

You use a mandrel bit with a sanding band, so this won’t actually touch the surface of the nail. Simply add your sanding band on top of the mandrel tip and you’re good to go.
Sanding bands

These are abrasive attachments that come in a variety of grit levels just like a nail file. They’re most commonly used for shaping and smoothing natural nails. You can also get large or mini sanding bands depending on your needs.
Barrel nail bits

Designed for completing surface work on the nail, you’ll need these in your kit. You can also use them for backfill cutting, shaping the nail and making smile lines. Don’t use these on the cuticle area though, because it’s too abrasive and can harm or hurt your client.
Needle drill bits

Also commonly referred to as the under the nail cleaner, this narrow bit is designed for:
- Gently cleaning the cuticle
- Removing dead skin on the sidewall
- General nail prep
Snake head cuticle bit

This is another type of cuticle cleaner bit. It’s ideal for preventing lifting by prepping and cleaning the cuticle.
Cone nail bit

These are too abrasive/coarse for the cuticle and natural nails, but they’re great for:
- Cleaning under the nail (pick a smaller cone)
- Cleaning and shaping the sidewalls
- Shaping toenails
Tapered barrel bit

Not to be confused with cone bits, these attachments come with a flatter top.
The main uses for a tapered barrel bit include:
- Cuticle
- Sidewall prep
- Surface work
- In-fills
Safety bit

Easily clean the cuticles and sidewalls with a safety bit. You can also use them for in-fills! Don’t forget to choose a coarseness that suits your need to avoid damaging the nail.
Flame/typhoon nail bit

It’s easy to see why this is called a flame bit! You’ll also see flame bits that look like the snake head cuticle bits above.
The smaller version is used for removing hangnails and cuticle work. Whereas the larger bit is more coarse and should be used on acrylics, polygel etc. only.
Ball shaped bit
Maintenance/backfill bit

The nail bit has a few uses, but mainly it’s for replacing white tips or redoing smile lines.
This tip should only be used on acrylics and not on natural nails.
5-in-1 carbide bit

The clue’s in the name with this one – it does it all! Use this for:
- Shaping acrylics
- Removing acrylic and hard gel
- Shortening nails
- Cleaning cuticles
- Prepping the nail bed
