CYC228 Dental 1:5 Fiber Optic Contra Angle Handpiece-X95 Style

1:5 speed-increasing gear transmission
Multiplies motor speed 5 times, max output speed up to 200,000 rpm, delivers turbine-level cutting efficiency with stable electric motor torque, perfect for fast precise tooth preparationnsk-inc.com.
Cellular glass fiber optic lighting system
Integrated high-transmittance light guide, matched NSK fiber optic electric motor outputs bright shadow-free light, clearly visualizes narrow posterior molar operation field; glass light guide resists aging under repeated sterilization cycles.
Quattro 4-way multi-directional inner water spray
Four surrounding water jets fully wrap the FG bur cutting area, rapid heat dissipation, thoroughly flush enamel/dentin debris to avoid dentin burn and postoperative hypersensitivity; built-in microfilter blocks water impurities to prevent spray clogging.
Lightweight medical titanium body with DURACOAT scratch-resistant coating
Biocompatible anti-allergy titanium outer shell, slim balanced ergonomic grip greatly relieves wrist fatigue during long aesthetic restoration procedures; smooth anti-scratch coating easy to wipe and disinfect.
NSK patented Clean Head double anti-retraction system
Dual-layer sealing blocks saliva, blood and debris backflow into internal gears and ceramic bearings, lowers cross-contamination risks and extends service life, meets global dental infection control standards.
Push-button FG bur chuck
Tool-free one-click replacement of standard Φ1.6mm friction grip burs; clamping force strengthens automatically under cutting load to prevent bur wobble or slippingnsk-inc.com.
Premium silent ceramic bearings & precision gear set
Ultra-low vibration and quiet stable rotation, high wear resistance for long-term daily high-frequency aesthetic restorative work.
135°C high-pressure autoclave sterilizable
The whole handpiece withstands hundreds of repeated high-temperature disinfection cycles without performance attenuation.
ISO standard E-type fiber optic interface
Universal coupling fully compatible with NSK NL400 / NLX Nano series fiber optic electric micromotors.
