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. Coarse grit is strong on skin, so keep speed low and contact feather-light.
4. Roll the ball gently around the cuticle area and sidewalls to lift and smooth dry skin.
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.

• Pressing the ball into the skin: Pressure concentrates on a small point; use light, rolling contact.
• Using coarse on delicate skin: Coarse grit can irritate thin cuticles; switch to a finer bit for sensitive clients.
• 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.

Why use a ball-shaped bit for cuticles?

A ball has no sharp edges, so it works smoothly around curves of the cuticle zone. Coarse grit suits tougher, thicker dry skin.

Is a coarse cuticle bit suitable for every client?

Coarse grit is best kept for clients with thick, stubborn dry cuticle. For thin or sensitive skin, a medium or fine bit gives a gentler result.

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.
