140mm Length x 23mm Diameter

A 120-gram aluminum pen with a centered weight distribution feels highly controlled, avoiding the "skittish" feel of cheaper, tip-heavy plastic units. It reduces grip tension and minimizes fatigue during detailed cuticle work.

Aluminum Alloy Housing

The housing is not just cosmetic—it acts as a heat sink and a vibration damper. Aluminum dissipates heat more effectively than ABS plastic, reducing the resonance that makes a drill sound louder than its motor actually is.

0-25,000 RPM Stepless Dial

Adjust the speed infinitely via the integrated control knob. Whether you need a slow, gentle rotation for natural nail buffing or higher speeds for gel removal, the dial provides exact control without jarring gear jumps.

Forward & Reverse Switch

Equipped with a two-way switch (Forward / OFF / Reverse), allowing for ambidextrous use and specific filing techniques that require opposite rotation.

6 Essential Bits Included

Includes needle-shaped, bullet train, conical, small cylindrical, large rounded, and sand ring shaft heads. Each bit is designed for specific tasks—from polishing the nail surface and removing cuticles, to shaping acrylics and removing calluses.
