NX 300S-170SH (40K)

High-Torque Performance up to 40,000 RPM: Engineered to provide stable, high-torque output across its entire speed range (0 to 40,000 RPM). This ensures smooth, continuous cutting and polishing performance even when processing dense laboratory materials like chrome-cobalt, zirconia, and hard dental acrylics.

Ergonomic & Lightweight #170SH Handpiece: The #170SH carbon brush handpiece features an advanced slim, non-slip grip design and weighs optimally to drastically reduce technician hand and wrist fatigue during long hours of laboratory fabrication.

Intuitive Dual Control & Auto-Cruise Mode: Offers dual-control operation, allowing users to toggle seamlessly between manual speed adjustment via the control box dial and variable speed foot pedal operation. Features an "Auto-Cruise" function that maintains a set grinding speed automatically to streamline repetitive workflows.

Bi-Directional Rotation (Forward/Reverse): Equipped with an electronic soft-switching reverse mechanism, allowing effortless switching between forward and reverse rotation modes to accommodate both right-handed and left-handed technicians, as well as multi-directional finishing tasks.

Advanced Intelligent Safety Protection: Built with an integrated electronic overload protection system that automatically cuts off power to protect the motor and handpiece circuitry from overheating or binding when excess pressure is applied.

Low Noise, Low Vibration Operation: Precision balanced internal engineering significantly minimizes operational noise and micro-vibrations, ensuring high tactile feedback and superior accuracy for intricate margins and crown adjustments.

Universal Laboratory Compatibility: Built on a standard HP shank platform ($\varnothing$ 2.35 mm) with a reliable twist-lock chuck mechanism, allowing for rapid, tool-free laboratory bur and polisher replacements.
