The Saeyang Marathon K-35 Main Unit Only is a professional nail drill control box designed for nail technicians who need stable daily performance, practical controls, and a reliable salon setup. This listing is for the main unit only, so it should be paired with a compatible handpiece before use.

Why Marathon K-35 Is a Strong Choice for Everyday Salon Work

This model includes a digital speed display, pause function, automatic power-saving system, and 6 built-in bit holders to help keep the workspace organized. It also supports manual control and an optional FS60 variable speed pedal, which is not included.

Compatible Handpieces and Pedicure Use

The Marathon K-35 main unit is listed as supporting compatible handpieces in the 25K to 45K RPM range. For pedicure work, one seller specifically notes that a handpiece with at least 3.0 Ncm torque is recommended.
