What Is an Electric Nail File?

An electric nail file—also called an e-file or nail drill—is a handheld rotary tool powered by a motor that spins interchangeable bits at variable speeds (0–35K RPM on pro models). Attach a sanding band to prep natural nails, a carbide barrel to debulk acrylic, or a buffing bit to create glass-like shine—all with the same device.

How Does an Electric Nail File Work?

Component	What It Does
Handpiece	Houses the motor, holds the bit. Medicool’s pro handpieces weigh less than 4 oz to reduce fatigue.
Control Box	Lets you set speed (RPM) and direction; cordless models hide the power pack in a hip-clip battery.
Bits	3/32-inch shank is industry standard; swap in seconds for sanding, carving, buffing, or polishing.
Foot Pedal (optional)	Hands-free speed & direction change—handy for sculpted sets.

5 Key Benefits Over Manual Filing

Speed & Efficiency – Cut 15–20 minutes off a full set or fill.
Consistency – Bit geometry delivers uniform pressure; no more uneven strokes.
Ergonomics – Less wrist strain; avoid carpal tunnel and HAVS.
Versatility – One device removes gel, sculpts acrylic, preps natural nails, and polishes.
Professional Finish – High-RPM buffing creates a flawless surface that blocks lifting.

Safety FAQ

Are electric nail files safe?
Yes—when used by a trained tech. The tool only removes what you touch.

Not when used correctly. Only the shine is removed. Use light pressure and fine grit bits.
