This model comes from the renowned Korean brand Saeyang , which has been recognized and recommended worldwide by cosmetologists, dental technicians, and prosthetists for nearly five decades.
The Marathon Multi 600 is known as an absolute top-of-the-line solution for long-term, heavy-duty use. Designed to operate smoothly all day long , it performs exceptionally well in complex tasks such as denture work, fine grinding, woodworking, and jewelry making . The combination of raw power, precision, and stability makes this milling machine a favorite in professional laboratories.

The heart of this nail drill is the extremely robust BM50S1 handpiece , equipped with an impressive torque of 7.8 Ncm . Combined with the high power of 100 W, this delivers exceptionally stable and powerful operation, even under heavy loads. The rotational speed is infinitely adjustable from 1 to an impressive 50,000 revolutions per minute , making the device suitable for both fine detail work and intensive machining.

The control unit is designed for maximum user-friendliness and safety . The clearly laid-out control panel features an illuminated on/off switch, a rotary knob for precise speed control, and the option to change the rotation direction to clockwise or counterclockwise. The innovative AUTO CRUISE function allows you to maintain a constant speed while operating with the foot or knee pedal , significantly improving ergonomics.
An added benefit is the integrated self-diagnosis function . This continuously monitors the device's proper functioning and displays any malfunctions via an error code on the digital display. This not only increases safety but also extends the machine's service life. A practical handpiece holder is included as standard.

The advanced TWIST-LOCK clamping system makes changing router bits quick, safe, and completely tool-free. A simple twist releases or tightens the bit. This saves time, prevents wear, and significantly increases working comfort, especially during intensive use.
