Description

The Saeyang Marathon N7 is designed for both manicures and complete pedicure services. With its strong motor and stable performance, it handles detailed nail work as well as full pedicure treatments with ease.

Reliable Performance

The N7 can be connected with handpieces of up to 40,000 RPM, giving you the power to file, shape, and polish quickly. Moreover, the variable speed control ensures precise results for every task, from buffing to cuticle care.

Built-In Safety

This model includes an automatic overload protection system, keeping the motor safe during long or intense sessions. In addition, the dust-proof switch cover adds extra durability for salon use.

Smooth and Quiet Operation

Thanks to advanced engineering, the handpiece works quietly with very little vibration. As a result, both technicians and clients enjoy greater comfort during treatments.

Flexible Controls

The N7 supports forward and reverse directions, even while running at speed. This feature, uncommon in most devices, gives you more flexibility in handling tricky angles. You can also connect an optional on/off or variable speed pedal for hands-free control.

Versatile Handpiece

The SH30N handpiece comes included. It delivers 2.9 Ncm torque, making it strong enough for everyday manicures and light pedicures. While slightly heavier than the SH30N, it provides extra power for professional use.
