Saeyang Marathon MULTI800 professional nail drill for manicure and pedicure
The high-quality Saeyang Marathon MULTI800 nail drill is a professional e-file designed for intensive manicure and pedicure treatments. Its powerful, precise operation helps nail technicians work on nails and cuticles, remove remnants of previous nail enhancements and prepare the nail plate for the next treatment.
With a maximum speed of 50,000 revolutions per minute, the Marathon MULTI800 is a powerful professional nail drill suited to demanding salon use. Its solid control unit, high-quality BS50C brushless handpiece, digital speed display and different control options allow precise control over every stage of treatment.
Its extensive functionality makes this 50,000 RPM professional nail drill particularly useful for nail studios, beauty salons and specialists performing multiple treatments daily who need efficient, ergonomic and flexible equipment.

Brushless BS50C handpiece – power, precision and working comfort
The BS50C handpiece is an important part of the Saeyang Marathon MULTI800. It is designed to sit comfortably in the hand, which is essential for precise work and longer treatments. Good balance and stable construction support controlled movements and reduce the need to use unnecessary force.
The handpiece reaches a maximum speed of 50,000 RPM. The user can adapt the rotation speed to the treatment, drill bit and preferred technique. One professional device can therefore handle both precise detail work and more intensive tasks.
Twist-Lock system for quick bit changes
The BS50C handpiece features a practical Twist-Lock mechanism for quickly inserting and changing suitable drill bits. This is particularly useful in a professional nail studio, where several bits may be used during one treatment.
The Twist-Lock system makes changing accessories quick and straightforward. It supports an efficient workflow and helps the technician move smoothly between different manicure or pedicure steps.
The solid handpiece construction contributes to stability and precise control, including during more intensive work. Its plastic housing also helps limit heat transfer, reducing noticeable warming during use.
The handpiece’s 150 cm cable provides freedom of movement around the workstation, making it easier to work comfortably and ergonomically from different positions.

Digital speed display and intuitive controls
The controls of the Marathon MULTI800 nail drill are designed for speed and clarity. The dial adjusts the speed precisely up to 50,000 revolutions per minute. The current setting appears on the digital display, allowing the user to check the selected speed while working.
A clearly readable speed is particularly useful in professional use. Different treatments, materials and drill bits may require different speeds. The digital display makes the setting easy to check and adjust when necessary.
The controls also select different drill functions. The user can switch operating modes, change the direction of rotation and temporarily stop the device using the pause function.
LED indicators for immediate device status checks
The integrated LED indicators show important information about the nail drill’s current settings and status. The technician can quickly see which function is active during treatment.
The indicators provide information about:
- the selected direction of rotation;
- activation of external control;
- the Auto Cruise function;
- the device’s pause status.
By bringing these functions together clearly, the Marathon MULTI800 offers extensive control without complicated operation. This matters in a professional environment where attention should remain primarily on the treatment and client.


Knee operation for hands-free control while filing
A distinctive feature of the Saeyang Marathon MULTI800 is its knee control. This allows the user to operate the device without repeatedly taking their hands away from the treatment area.
The dedicated control allows the nail drill to be activated or stopped with the knee. It can considerably improve workflow when both hands are needed for precise work. During intensive manicure and pedicure treatments, this control method can support a more natural and efficient working posture.
Auto Cruise for a constant selected speed
The Auto Cruise function complements knee and external control. When enabled, the selected speed can be maintained after pressure on the control is released, so the user does not need to apply continuous pressure to maintain the same speed.
This also allows the control unit to be positioned conveniently, for example beneath or near the workstation. The user gains more free worktop space while retaining control of the nail drill.
The combination of knee control, Auto Cruise and digital speed adjustment makes the MULTI800 particularly suitable for professionals who value ergonomics, speed and flexibility in their daily work.

Modern design for a professional nail studio
The Saeyang Marathon MULTI800 professional nail drill combines advanced functionality with a modern appearance. Its futuristic housing in beige and brown tones features a subtle speckled finish, rounded shapes and a matte texture.
The device therefore looks professional and fits well in modern nail studios, beauty salons and specialist treatment rooms. A well-designed appearance is a useful advantage in salons where equipment remains visible at the workstation.
The housing is made from high-quality materials chosen for durability and easy maintenance. Its smooth surfaces are practical to clean, which is important in daily professional use.
The base has rubber non-slip feet. They help keep the control unit stable on the work surface while protecting that surface from scratches.
Versatile use in professional manicure and pedicure
With its high maximum speed and precise adjustment, the Saeyang nail drill can perform a range of professional nail-care tasks. Depending on the fitted bit and selected setting, it can be used at different stages of manicure and pedicure treatments.
The Marathon MULTI800 supports tasks such as:
- preparing the natural nail plate;
- precise work around cuticles;
- removing remnants of previous nail enhancements;
- working on and correcting artificial nail products;
- shaping and refining during manicure;
- professional work during pedicure treatments;
- finishing nail enhancements with suitable drill bits.
Always choose a suitable bit, appropriate speed and correct technique for each application. This supports controlled, precise professional use.
Developed for intensive professional use
In a busy nail studio, a nail drill is often used for several hours a day. The combination of a solid base unit, brushless BS50C handpiece, precise speed control and ergonomic operation makes the MULTI800 well suited to demanding professional users.
A high maximum speed does not mean every treatment should be performed at maximum speed. The wide adjustment range allows the drill to be adapted precisely to each task. The professional has one powerful machine for both detailed and more intensive work.
