Saeshin Strong Drill 210 / 120 Silver 30K RPM Nail Drill

The Saeshin Strong 210 / 120 Silver is a professional electric nail drill designed for nail technicians who need stable speed, reliable control, and a compact salon-ready setup for daily manicure and pedicure services. The most consistent sources for this exact 210/120 set position it as a 30,000 RPM Korean-made system with the Strong 210 control box and 120 handpiece.

Why It Works Well for Professional Use

This model is a good fit for nail techs who want a classic corded e-file with dependable salon performance instead of a portable battery setup. The 120 handpiece is positioned as a lighter, more compact option in the Strong range while still maintaining enough torque for regular manicure and pedicure work.

120 Handpiece

The 120 handpiece is the main working part of this set. Manufacturer and seller pages list it at 30,000 RPM, with about 2.8–3.0 Ncm torque, and weight ranging from roughly 162 g to 265 g depending on listing/version details; the manufacturer-linked source for 120 II gives 162 g and 2.8 Ncm, while seller pages for the set often cite a heavier figure. For a cleaner product page, I would use the more stable core claims: 30K RPM, compact size, and professional-use handling.
