Included drill bits and sanding bands
The kit ships with a diverse set of 15 bits and 75 sanding bands so you can handle everything from coarse removal to finish work. Those extras make it a practical starter kit for a new tech and a compact backup for a pro on the move.
For finishing and around-the-cuticle work, many techs pair an e-file with a fine cross-cut or tapered finishing bit; if you need a finishing-style bit, consider a fine cross-cut drill bit designed for sealing and smoothing details fine cross-cut drill bit.
Battery, LCD and charging details
Power management is a notable part of this design. Two batteries are provided so you can use one while charging the other, reducing downtime between clients or during long at-home sessions. The LCD reports both the exact RPM and remaining battery so you can avoid surprises mid-service. A full recharge is reported to take roughly 2–3 hours and the expected operating window is approximately 8–10 hours from a full charge.
Practical use guidance
Because the drill supports a wide RPM range and forward/reverse rotation, start slow when learning a new bit or technique and increase speed only as needed. Use the LCD to confirm the RPM setting rather than estimating by feel. Swap batteries between services to keep one unit topped up while the other is in use.
- Begin with lower speeds for natural nails and precision cuticle work.
- Increase RPM for bulk acrylic or gel removal tasks, while maintaining control.
- Use forward and reverse to match your dominant hand and the direction that keeps the bit cutting safely away from the skin.
Comfort, build and vibration control
The handpiece uses an aluminum-alloy shell and a balanced motor housing. Compared with an all-plastic body, that construction is intended to reduce heat buildup and vibration, which helps when holding the tool through longer sets or multiple clients. The device is described as lightweight and compact, making it simple to hold for extended periods and easy to store in a kit bag for mobile work.
Suitability and workflow fit
This cordless e-file is suitable for:
- Beginner nail technicians who want a full set of starter bits and sanding bands.
- Experienced techs who need a compact cordless back-up for travel or home visits.
- At-home users who do regular acrylic, gel or dip powder maintenance and prefer a portable tool.
Limitations and safety notes
As with any high-speed electric nail tool, monitor the LCD for RPM and battery level so you maintain consistent performance. The reversible motor supports both handedness, and the aluminum-alloy handpiece is designed for lower heat and vibration compared with bare-plastic alternatives. Those design choices aim to make the device steadier to hold, but proper training and careful technique remain essential when working close to the natural nail and skin.
What this package does not add
- Specific professional warranties or external certifications are not listed here.
- It does not replace formal training; the tool supplies hardware and consumables but skill and safe technique must come from instruction and practice.
Conclusion
If you need a portable, cordless e-file with a high top speed and a complete beginner-friendly accessory pack, this model offers an appealing balance of features: variable 0–40,000 RPM, forward/reverse, an LCD for RPM and battery readout, dual rechargeable batteries with quick charging, and a robust aluminum-alloy handpiece that aims to reduce heat and vibration. The included 15 bits and 75 sanding bands make the kit ready to use out of the box for acrylic, gel, dip powder and natural nail services. For many mobile techs and at-home users, that combination is a practical compromise between portability and capability.
