The COSLUS E51 Electric Nail Drill is a rechargeable, professional-grade e-file that delivers up to 40,000 RPM with 40-speed precision for salon-quality shaping, gel removal, and nail-art practice.

Compact but powerful, the COSLUS E51 pairs a high-torque motor with a detachable handpiece, a clear LCD, and long battery life to handle everything from gentle polishing to heavy gel and acrylic removal. Designed for both beginners and experienced technicians, this cordless drill comes with a charging stand, a set of seven 3/32" bits and 31 sanding bands, plus a belt clip and storage base to keep tools organized whether you’re working at home or in a salon.

How does the E51 balance power and stability for detailed nail work?

The E51 uses an upgraded high-torque motor with precision bearings that minimize vibration, providing steadier rotation at high speeds so you can work on intricate designs without chatter. Low noise and low heat output let you run longer sessions while maintaining control over delicate cuticle and sculpting tasks.

• Up to 40,000 RPM with consistent torque for heavy-duty tasks
• Precision bearings reduce vibration for smoother results
• Low heat and low noise for comfortable extended use

What speed ranges should I use for different manicure jobs?

The E51’s 40-level speed control maps to common salon tasks so you can pick the right setting quickly. Lower levels are ideal for filing and finishing, mid-levels handle gel and acrylic removal, and higher levels are reserved for shaping and thick material sanding.

• Levels 0–10: gentle polishing, prepping, and finishing
• Levels 11–20: efficient gel and acrylic removal
• Levels 21–30: shaping, trimming, and callus work
• Levels 31–40: high-precision sculpting and heavy grinding

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

The built-in rechargeable battery supports extended cordless sessions, with typical continuous use between 12 and 20 hours depending on speed and task intensity. A fast Type-C charging port refuels the unit in about 2.5 hours, while the LCD shows remaining power so you can avoid interruptions.

• 12–20 hours of cordless operation under common usage patterns
• Fast Type-C charging completes in approximately 2.5 hours
• LCD displays battery level, rotation direction, and speed setting

What accessories and storage features come with the kit?

The COSLUS E51 kit includes a practical selection of bits and sanding bands plus a stable storage base to keep everything organized during work or transport. The lightweight handpiece, belt clip and a neat gift box make the set suitable for mobile technicians or anyone starting nail-art practice.

• Seven professional 3/32" drill bits for shaping, carving, and cuticle work
• 31 sanding bands covering varied grits for removal and finishing
• Charging stand with storage base and a portable belt clip
