Cordless nail drill Saeyang Marathon K35S with brushless BS30S handpiece

The perfect drill for mobile work

The battery-powered Saeyang Marathon K35S nail drill with brushless BS30S handpiece is built for professionals who value freedom of movement and reliability. Thanks to its compact size and efficient battery, it works just as well in the salon as on home visits. The drill makes it easier to work on nails and cuticles and gives a precise base for the next stages of the treatment. The battery lasts up to 10 hours on a single charge – a real advantage on a busy working day.

Brushless BS30S handpiece

The ergonomic BS30S handpiece is well balanced, sits securely in the hand and gives precise control of your movements. The brushless motor means quieter operation, greater durability and a longer service life. Reduced vibration helps prevent hand fatigue, even during long treatments. The Twist-Lock system allows quick and easy bit changes without tools. The flexible coiled cord stretches to over 220 cm, giving you freedom of movement.

Digital display and intuitive controls

The large, clear display shows the key operating values: current speed, battery level and selected direction of rotation. The dial with Click function, which signals when the drill is switched on and off, adjusts speed smoothly up to 30,000 rpm, so you can easily match the setting to the treatment. Next to the dial are a direction switch and a pause button that make everyday use easier.

Comfortable to use every day

Quiet operation makes the treatment more pleasant for both you and your client. The built-in 2850 mAh lithium-ion battery provides up to 10 hours of use on one charge, so you can complete many treatments without reaching for the charger. Charging is done with the included USB-C cable.

Compact and modern design

The minimalist white housing is made of durable plastic that withstands daily use and is easy to keep clean. Its small size and light weight make the drill easy to carry and to fit on any workstation – ideal for technicians offering home visits too.
