MelodySusie Pen-Shaped Cordless Nail Drill PM170F — 30,000 RPM, 30-Speed Lightweight Handpiece for Beginners

The MelodySusie PM170F combines a slim, ergonomic handpiece with cordless convenience and a coreless motor that balances power with low noise and low vibration. It’s built to help hobbyists, beginners, and home users shape, buff, and maintain nails and calluses without bulky cords or complicated setups. The unit ships with multiple bits and sanding bands so you can start basic nail prep and light callus work right away.

How does the PM170F perform for basic nail and cuticle prep?

The PM170F offers up to 30,000 RPM across 30 adjustable speed settings, so you can match rotation to delicate tasks like cuticle cleanup or faster shaping. The forward/reverse control supports both right- and left-handed use, and the included bits and sanding bands cover common beginner needs.

• 30-step speed control from 0 to 30,000 RPM
• Forward and reverse rotation for ambidextrous use
• Includes 5 nail bits and 25 ultra-fine sanding bands
• Pause function and display screen for easy monitoring

Is the device comfortable and safe to use for extended sessions?

The slim, pen-style handpiece is lighter and smaller than an electric toothbrush, reducing hand fatigue during longer sessions. Built-in overload protection and a coreless motor with improved heat dissipation help maintain stable performance while minimizing vibration and noise.

• Slim grip for improved control and reduced slips
• Low-vibration, quiet operation for comfortable use
• Overload protection to prevent motor strain
• Smart heat dissipation for safer, longer use

How long does the battery last and how quickly does it charge?

The integrated 320 mAh battery fully charges in about one hour and provides roughly 4 to 6 hours of typical use depending on speed settings. Fast charging and cordless operation make it convenient for travel and quick touch-ups between salon visits.

• 320 mAh rechargeable battery
• Full charge in ~1 hour
• 4–6 hours of battery life per charge depending on intensity
• Cordless design for portability and home use

What tasks should I use this drill for and which bits are recommended?

The PM170F is recommended for lighter nail and skin tasks such as grinding, smoothing, shaping, shortening, and polishing natural and artificial nails, plus gentle callus or dead-skin removal. Use finer bits for delicate work and avoid heavy cutting bits to protect natural nails.

• Best for manicure and pedicure prep — shaping, buffing, shortening
• Recommended bits: cuticle-clean, flame, needle, small cylinder, micro ball
• Includes 25 ultra-fine sanding bands for smoothing and polishing
• Avoid heavy-duty bits for thick acrylic removal — stick to lighter bits

Who is this for? The MelodySusie PM170F is aimed at nail-art beginners, home beauty users, and anyone wanting a portable, easy-to-handle e-file that balances power and precision. It’s also a good fit for travel, touch-ups, and families who want a single cordless tool for basic manicures and light pedicure care. Professionals who need heavy-duty acrylic removal or salon-grade continuous duty might prefer a more powerful, corded alternative, but for at-home nail maintenance and nail-art practice, the PM170F is purpose-built for comfort, control, and convenience.
