The PrecisionCore™ film
Precision,
in motion.
The PrecisionCore™ experience in 21 seconds — salon-grade precision, at home.
45 progressive steps
45,000 RPM.
Under absolute control.
From the gentlest polish (1–15) to the densest builder gel (31–45), every step answers your hand precisely. The dial turns under your finger, the display confirms, and the speed holds — even deep in the material.
“Speed only matters when it obeys.”
3-petal chuck · Aluminium handpiece
Locked. Balanced.
Silent.
The self-locking chuck secures the bit with a single twist — no stray vibration, no whistle. The aluminium handpiece stays cool and steady in your hand, minute after minute.
“You're holding an instrument, not a tool.”
Cordless · 1,200 mAh battery
3 hours of freedom.
Anywhere.
Three hours of work per charge, a 2.5-hour USB-C recharge, the level always on screen. Vanity, sofa, weekend away — your ritual follows you, never hunting for a socket.
“Cordless. Stress-free. Limitless.”
Your routine, your rules
A pro touch for every step.
Prepping the nail, sculpting the material, removing the most stubborn gel — PrecisionCore™ carries you through every step of your routine, without exception.

45 steps, 3 zones of mastery
Confidence, step by step.
Always start low, move up step by step. Precision comes from the setting, not from force — the golden rule of the PrecisionCore™ Atelier.
The 3-petal chuck accepts any standard bit —
today's sanding bands and the ones you'll choose tomorrow.
How it works
Set your bit
Twist the ring left, insert the bit to the stop, lock it right. The self-locking 3-petal chuck holds it perfectly straight — zero lateral wobble, zero tools.

Choose your step
Delicate zone (1–15) for natural nails and cuticles, Standard (16–30) for gel polish removal, Intensive (31–45) for thick gel. The golden rule: start low, move up step by step.

What they say · what they confirm
Nine years as a nail tech, and I'm demanding about equipment. The rotation is stable, the chuck doesn't move a micron, the heat is under control. This is a true salon e-file, in a format that fits in a drawer.
I was told e-files were for professionals only. With the speed steps and the guide, I did my first removal in twenty minutes, stress-free. My nails have never looked this clean.
I broke two budget e-files before this one. No comparison: it doesn't vibrate, it doesn't heat up, and step 12 on my cuticles is unbelievably gentle.
of professionals who tested PrecisionCore™
recommend it to their clients.
Study conducted with 47 nail professionals · Europe 2025
It's the first consumer e-file I'd recommend in a salon. The rotation stays stable under load, the chuck is flawless. Clients who own one no longer book removals with me.
I've trained dozens of beginners, and the obstacle is always the same: fear of the tool. The 45 steps change everything — you start gently, you build, you master it. It's the instrument I recommend in training.
What convinced me is the handpiece. Aluminium, balanced, no stray vibration — after an hour of work, your hand isn't tired. That's rare, even in professional equipment.

Product & Usage
Yes — it was designed for you. The 45 speed steps let you start very gently (Delicate zone, steps 1–15), and the included PrecisionCore™ Atelier guides you chapter by chapter: which bit, which speed, which angle, how much pressure. Expect 5 to 10 sessions to feel fully confident — the guide walks you through every one.
Stability. Entry-level e-files slow down, vibrate or heat up the moment the bit touches material. PrecisionCore™ holds 45,000 RPM under load, adjusts across 45 progressive steps instead of 5 notches, and its 3-petal chuck locks the bit perfectly straight. Add the heat-dissipating aluminium handpiece, the included masterclass and the lifetime warranty — it is simply a different class of instrument.
No — as long as you follow the golden rule: always start lower than you think and move up step by step. The Delicate zone (1–15) is dedicated to natural nails and cuticles. The bit never touches skin, only the nail plate, in short continuous passes. Everything is covered in the PrecisionCore™ Atelier.
Yes — that is its core job. The Standard zone (16–30) is calibrated for gel polish removal: top coat and colour are filed away in short passes, without harsh files or prolonged acetone soaking. For thick builder gel and acrylic, switch to the Intensive zone (31–45). Forward/reverse rotation (F/R) lets you work each side of the nail in the right direction.
About 3 hours of use per charge — enough for several complete sessions. Recharging takes 2.5 hours via the included USB-C cable, and the LED display shows the battery level at all times (P00 → P99). For safety, the e-file cannot be used while charging: the display warns you before you run out.
No. The machined aluminium handpiece dissipates heat and dampens vibration, and the 3-petal chuck keeps the bit perfectly centred — no whistling, no trembling in your fingers. You can hold a conversation during your session.
