1. Insert the bit fully into the handpiece and lock it; run it briefly at low speed to check it spins true.
2. Hold the handpiece like a pencil and position the bit at the correct angle to the nail surface.
3. Extra fine grit is for finishing, so work at a comfortable moderate speed with very light, sweeping passes.
4. Keep the barrel flat to the surface for broad shaping, and use the chamfered edge carefully along the cuticle area and sidewalls.
5. Keep the bit moving in smooth, light passes and never pause in one spot.
6. Refine with a finer bit or buffer before applying colour or top coat.
7. After the service, brush away debris, clean and disinfect the bit according to your local regulations, and dry it fully before storing.

• Tilting the barrel: Angling the barrel digs its edge into the product; keep it flat for even removal.
• Using extra fine for shaping: Extra fine is too gentle to change shape efficiently; shape first with a coarser grit and save this bit for the final finish.
• Pausing in one spot: Holding the bit still concentrates friction and heat; keep it moving in smooth passes.
• Pressing too hard: Pressure creates heat and discomfort; use light contact and let the grit do the work.
• Skipping bit cleaning: Packed debris dulls the bit and is unhygienic; brush, clean and disinfect after every client.

What does the chamfered edge actually do?

A chamfer is an angled edge at the top of the barrel. It reduces the sharp corner that can cut into the product or skin, giving you more control when working towards the cuticle area.

Do I still need a buffer after an extra fine bit?

An extra fine bit leaves a very smooth surface that is ready for most top coats. Some technicians still give a quick buff for a high-gloss no-wipe finish, depending on the product system.

What is the difference between a ceramic and a carbide bit?

Ceramic bits are lightweight and non-porous, which makes them easy to clean and a popular choice for smooth filing. Carbide bits cut with sharp flutes and are often preferred for fast removal; many technicians keep both and choose by service.

My client feels heat during filing. What should I change?

Heat means friction is building in one place, so lower the speed, lighten your pressure and keep the bit moving. Lifting off the nail briefly between passes also lets the surface cool.

How do I know when the bit needs replacing?

If you need more pressure or more passes than usual to get the same result, the bit is worn or clogged. Clean it thoroughly first; if performance does not return, replace it.
