1:1 direct drive equal-speed transmission
Rotating speed matches the electric motor output, stable uniform rotation for trimming, polishing and minor cutting operations, no speed amplification or reduction.
Cellular glass fiber optic lighting system
High-transmittance built-in light guide, matched NSK fiber optic electric motor delivers bright shadow-free illumination (25,000 Lux), clearly visualizes posterior deep oral operation areas.
Single built-in inner water spray channel
Internal integrated water pipeline sprays water directly onto the bur cutting point, continuous cooling flushes debris, prevents dentin overheating and postoperative sensitivity; equipped with built-in microfilter to block water impurities and avoid spray blockage.
Lightweight titanium body with DURACOAT scratch-resistant coating
Medical biocompatible titanium material, around 30% lighter than stainless steel handpieces; smooth anti-scratch coating, balanced ergonomic grip to relieve wrist fatigue during long continuous treatment.
NSK patented Clean Head anti-retraction system
Double-layer sealing anti-backflow structure blocks saliva, blood and debris from entering internal gears and bearings, reduces cross-contamination risk and extends service life, meets global dental infection control standards.
Push-button quick bur chuck
Tool-free one-click replacement of standard Φ2.35mm CA burs; clamping force increases automatically under load to prevent bur wobble or slipping during polishing and trimming.
Precision ceramic bearings & low-vibration gear set
Low noise, ultra-smooth rotation, high wear resistance, stable performance under long-term frequent clinical use.
135°C high-pressure autoclave sterilizable
Whole handpiece supports repeated high-temperature disinfection cycles without light guide and gear performance degradation.
ISO standard E-type fiber optic interface
Universal coupling compatible with all mainstream NSK fiber optic electric micromotors (NL400 series etc.).
