Description

The Saeyang SH20N is a professional replaceable handpiece designed for nail technicians who need light weight, stable speed, and comfortable daily use. The block at the top of your draft about Strong 210 / 105L is unrelated to this product; the SH20N is a separate Saeyang handpiece model.

Key Features

• Up to 30,000 RPM
• 2.7 Ncm max torque
• 3-prong connector
• 146 g weight
• 128 × 26 mm body size

Why It Works Well for Professional Use

This handpiece is best positioned for nail techs who want a lighter, easier-to-control option for routine manicure work and lighter salon services. Several seller pages describe the SH20N as one of the lighter Saeyang handpieces and emphasize its smooth, quiet operation.

Compatibility

The SH20N is commonly listed as compatible with M3, Escort III, and K35 Mini, and some sellers also mention broader compatibility with Marathon systems that use the same connector style. The safest page wording is that it is a 3-prong Saeyang/Marathon-compatible handpiece for supported control boxes.
