Why It Works Well for Professional Use

This setup is a strong fit for nail techs who want more speed and torque than standard 30K–35K systems. Seller listings for the 105LN consistently position it as a more powerful handpiece for salon work, especially for removal, shaping, correction, and pedicure procedures where stable performance under load matters.

105LN Handpiece

The 105LN handpiece is the main strength of this model. Official and seller sources describe it with 45,000 RPM, 4.0 Ncm torque, 199 g weight without cord, and a 3/32" collet chuck, making it a stronger option for more demanding work while still staying ergonomic enough for long sessions.
