1. Insert the bit fully into the handpiece and lock it; run it briefly at low speed to check it spins true.
2. Gently push back the cuticle to reveal dry, dead skin on the nail plate.
3. Medium grit works well at low speed with light, sweeping contact.
4. Use the rounded cone in light circular or sweeping motions around the cuticle area.
5. Work in short, light strokes around the cuticle area, keeping the bit moving at all times.
6. Stop as soon as the area looks clean; do not work into live tissue.
7. After the service, brush away debris, clean and disinfect the bit according to your local regulations, and dry it fully before storing.

• Staying in one area too long: Lingering creates heat on the skin; keep moving around the cuticle zone.
• Pressing harder instead of changing bits: If medium is not lifting the skin, pressing harder causes irritation; use a coarser bit for stubborn areas.
• Running the speed too high: High speed near skin causes heat and discomfort; keep speed low for cuticle work.
• Working on live tissue: Cuticle bits are for dry, dead skin only; stop once the area is clean.
• Using the wrong rotation direction: Moving towards the skin increases the risk of nicks; choose the direction that moves away from the skin on each side.

Is a rounded conical bit good for everyday prep?

Yes, its rounded shape and medium grit make it a versatile choice for routine cuticle cleaning and smoothing. It is less aggressive than a pointed flame bit.

Is medium grit enough for regular maintenance clients?

Yes, medium suits most regular clients whose cuticles are maintained every few weeks. Reserve coarse for neglected or very thick dry skin.

How do I clean a diamond cuticle bit?

Brush away skin debris, then clean and disinfect according to your local hygiene regulations and dry completely. Skin debris trapped in the diamond surface reduces its effectiveness, so clean thoroughly after every client.

Should I do e-file cuticle work on wet or dry skin?

E-file cuticle work is usually done on dry skin, which makes dead tissue easier to see and remove precisely. Soaking softens the skin and makes it harder to judge where the dead tissue ends.

Why does my client's cuticle area look red after the service?

Redness usually means the speed was too high, the pressure too firm or the bit touched live skin. Reduce speed, lighten your touch and stop as soon as the dead skin is removed.
