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. Fine grit removes little product per pass, so use a steady moderate speed and keep the bit moving rather than pressing harder.
4. Keep the barrel flat and sweep across the surface to even out high spots and refine thickness before top coat.
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 refinement.
• Pressing harder to speed up a fine bit: Extra pressure creates heat rather than faster removal; switch to a coarser grit if more product needs to come off.
• 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.

• Bit type: Large barrel, cross spiral cut
• Grit: Fine
• Material: Tungsten carbide
• Shank size: 3/32" (fits most professional nail drills)
• Finish options: Gold
• Best for: Surface refinement, thickness reduction, smoothing uneven areas and pre-top-coat prep
• Care: Brush, clean and disinfect between clients; dry fully before storing
• Use: Professional nail services

Is this bit suitable for dip powder?

Yes, the cross-spiral cut is designed for smoothing acrylic, gel and dip surfaces. Keep speed moderate on dip to control dust and heat.

Can a fine bit remove product, or is it only for finishing?

A fine bit removes product slowly, which makes it useful for light thinning and blending, but it is inefficient for heavy removal. Use it after a coarser bit to refine the surface and smooth out scratches.

How do I keep a tungsten carbide bit cutting well?

Brush out dust after every client, then clean, disinfect and dry the bit fully before storing. Packed debris in the flutes is the most common reason a carbide bit starts to feel dull.

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.
