The Saeshin Strong 210 / 105L is a professional nail drill designed for nail technicians who need stable speed, smooth control, and reliable daily performance for manicure and pedicure services. The Strong 210 control box is paired with the 105L handpiece, and seller sources for this combination consistently describe it as a Korean-made professional system with 65W power, DC 0–32V output, and a compact desktop format.

Why Strong 210 / 105L Works Well for Salon Use

This model is built for controlled professional work rather than basic occasional use. The 105L handpiece is described as having up to 35,000 RPM, 3 N·cm torque, and a lightweight body designed for smoother filing with less fatigue during longer sessions. The Strong 210 base also supports hand/foot mode switching, which makes it practical for technicians who prefer hands-free workflow.

The 105L Handpiece and Bit Compatibility

One of the key advantages of this setup is the Twist-Lock collet system, which allows quick bit changes and supports standard 2.35 mm / 3/32" drill bits. The 105L handpiece is listed with a length of 153 mm, a weight of about 190 g, and torque designed to help maintain performance under load at lower speeds.
