The Saeyang Marathon N7 is a powerhouse for the demanding professional. With continuously adjustable speed up to 40,000 RPM and a powerful torque of 4.5 Ncm, you can effortlessly perform both refined manicures and intensive pedicure treatments. The motor delivers constant power without performance loss.

The SDE-SH37L handpiece is known for its superior balance and grip. Weighing only 210 grams and operating vibration-free, you can work comfortably all day without hand fatigue. Thanks to the Twist-Lock system, you can change milling bits (Ø 2.35 mm) in one smooth motion without additional tools.

Safety is central to the N7. The device is equipped with an automatic safety system that immediately shuts down the motor in case of overload, with a clear LED warning. Additionally, a dust cover protects the on/off switch from filing dust ingress, significantly extending the transformer's lifespan.

For maximum workflow, you can easily switch between manual operation and operation via the included FS60 foot pedal. This allows you to control the speed with your foot, leaving both hands free for the client. Furthermore, you can switch between left and right rotation with the press of a button.

Despite its industrial performance, the N7 has an elegant and compact design that fits perfectly on any workbench. The module includes a built-in bit holder, so you always have your most frequently used burrs organised and within reach. The digital display provides you with exact insight into your speed at all times.
