Why It Works Well for Professional Pedicure Use

This model is best positioned for nail techs who want more power than standard 30K–35K sets. Multiple seller and distributor pages specifically recommend the B140D + 105LN for dry pedicure and heavier salon workloads because the 105LN is one of the stronger brushed Saeshin handpieces in this range.

105LN Handpiece

The 105LN handpiece is the main performance driver in this set. Across the sources, it is consistently listed at 45,000 RPM, 4.0 Ncm torque, 199 g without cord, and about 153 × 29 mm, with standard 3/32" / 2.35 mm bit compatibility.
