The ideal milling machine for mobile services
The compact Saeyang Marathon K48 PRO cordless nail drill with a brushless motor is a reliable tool that’s perfectly suited for mobile manicurists. It ensures precise nail and cuticle care, creating the perfect foundation for subsequent styling steps. On a single charge, it provides up to 8 hours of comfortable use.

Brushless Head BS35
The slim BS35 head fits comfortably in the hand and allows for comfortable, precise work. Thanks to its optimal balance and significant vibration reduction, using it does not cause excessive hand fatigue, allowing you to perform procedures that last even many hours. It is equipped with an easy-to-use Twist-Lock system that allows for quick and easy bit changes. As a result, working with the device becomes extremely simple and intuitive—a feature that even the most demanding users will appreciate.

Intuitive operation with a clear LCD display
Using the knob, you can easily adjust the head speed up to 35,000 revolutions per minute, allowing you to conveniently tailor the speed to your individual needs and ensuring comfort while performing various procedures. Pressing the knob allows you to instantly stop and restart the device (pause function), giving you complete control over the workflow. Convenient buttons on the side allow you to quickly switch control of the device to the foot pedal and change the direction of rotation, making work even easier. LED indicators on the display show the rotation direction, battery status, pedal activation, and pause status. The tool is equipped with overload protection that prevents the motor from overheating, ensuring greater safety during operation and extending the tool’s service life.

Precise features for user comfort
The drill operates quietly, eliminating annoying noise and ensuring comfort for both the practitioner and the clients. The built-in 2850 mAh battery allows for up to 8 hours of operation on a single charge. In addition, the device is equipped with an automatic power-saving mode that prevents the battery from draining. The device was designed with ergonomics in mind—a convenient button layout and intuitive operation ensure that every treatment proceeds smoothly.

A compact, aesthetically pleasing device
The minimalist-style plastic housing in shades of white ensures durability and easy cleaning, while also giving the workspace a visually appealing look. Its compact size and lightweight design make this router ideal for both small workspaces and transport—particularly useful for mobile services. The rubberized feet provide greater stability, preventing the device from slipping during operation, which promotes safe and comfortable use.
