Saeyang Marathon Handy 700 BM50S1 FS60N 2-in-1 Brushless Micromotor
The Saeyang Marathon Handy 700 is a Korean prosthetic-grade device that is also suitable for cosmetology. The brushless BM50S1 handpiece operates smoothly from 1,000 to 50,000 rpm, while the base with 2 ports allows you to connect two handpieces simultaneously and switch between them without reconnecting cables.

Key features
- brushless BM50S1 handpiece with 7.8 Ncm of torque
- smooth speed adjustment from 1,000 to 50,000 rpm
- 2 handpiece ports - quick tool changes without reconnecting cables
- FS60N foot control with speed adjustment included
- Auto Cruise and self-diagnostic function
- Twist-Lock handpiece for one-motion bur changes
- noise reduction system - 20% quieter than conventional models
Two handpieces on one base
The second port on the back of the base accommodates another handpiece, allowing you to alternate between two tools - for example, one handpiece for preparation and another for polishing - without reconnecting cables. This is why the set is designated 2-in-1.

Power and smooth operation
The 100 W motor maintains speed under load, while the brushless handpiece design also reaches low speeds of around 1,000 rpm, useful for delicate work. The noise reduction system lowers the sound level by 20% compared with conventional models.

Hand or foot control
Speed can be adjusted using the dial on the base or the FS60N foot control with built-in adjustment. Auto Cruise lets you set a constant speed when working with the pedal, while self-diagnostics displays an error code on the digital screen and identifies the faulty area.

Twist-Lock and stand
The bur is changed with a single movement of the Twist-Lock handpiece - turn left to unlock and right to secure it. The included stand protects the handpiece during breaks, while the built-in overload protection and replacement fuse protect the electronics.
