The Saeyang Marathon SH37LN Handpiece (40,000 RPM) is a high-performance professional nail drill handle engineered in Korea for advanced manicure and pedicure services. Designed for nail technicians who demand power, precision, and long-term durability, this handpiece delivers exceptional performance even under heavy salon use.
With a maximum speed of 40,000 RPM and 4.5 N·cm torque, the SH37LN provides strong, consistent rotation without power drops, making it ideal for acrylic removal, hard gel shaping, and intensive smart pedicure procedures.
The advanced internal motor system ensures low vibration and low noise, allowing for smoother, more controlled work and reduced hand fatigue during long sessions. Its lightweight and ergonomic design (only approx. 210g) provides maximum comfort and precision for detailed nail work.
Equipped with a Twist-Lock mechanism, the SH37LN allows quick and secure bit changes, improving workflow efficiency and saving time in busy salon environments.
Built with a cooling system to minimize heat generation, this handpiece is designed to operate continuously without overheating, extending motor life and ensuring reliable long-term performance.
Compatible with standard 3/32” (2.35 mm) drill bits, it offers full versatility for all nail procedures—from cuticle work to product removal and surface refinement.
Why This Handpiece Stands Out
• Designed for high-load procedures like smart pedicure
• Stronger torque than standard handpieces — no stalling under pressure
• Professional Korean engineering = longer lifespan vs cheaper alternatives
• Stable performance even at max speed
• Perfect upgrade for Marathon systems (N7, Escort, Champion series)
