Saeyang Marathon N7 Nail Drill Machine – Professional 40,000 RPM E-File for Manicure & Pedicure

When precision, power, and reliability matter most, the Saeyang Marathon N7 Nail Drill delivers. Made in Korea by Saeyang, a global leader in professional nail equipment, the Marathon N7 is a high-performance E-file designed for both manicure and complete pedicure services. With its powerful SH37L (M45) handpiece, robust 40,000 RPM speed, and advanced safety features, the N7 is a salon-grade machine trusted by professionals worldwide.

Built for Professional Pedicure and Manicure Services

Unlike basic E-files, the Marathon N7 is engineered to handle full combined pedicure treatments. Its powerful torque and stable operation make it ideal for removing thickened toenails, calluses, and hardened skin, as well as shaping, refining, and polishing natural nails or enhancements.

Thanks to its automatic overload protection system, the device safeguards itself from overheating or damage during long or intensive procedures. This not only extends the life of the machine but also provides peace of mind for technicians performing demanding treatments.

Precision Speed and Direction Control

One of the standout features of the N7 is its ability to switch directions and adjust speed while the handpiece is still running. This flexibility is uncommon in most devices (only the Marathon K35 Mini shares this function), making the N7 especially versatile for busy salons.

• With variable speed settings up to 40,000 RPM, technicians can tailor the drill’s performance to match the task at hand:
• Low speed for delicate cuticle work and buffing
• Medium speed for filing and shaping natural nails
• High speed for pedicure services, enhancements, and bulk removal
• This precise control ensures smooth, efficient results across a wide range of applications.
