NSK-Compatible High-Speed Dental Handpiece – LED Light, Push Button | Quick Connect

$429 high-speed handpiece compatible with NSK-style quick-connect couplers. The GoldGreen Dental NSK-Compatible High-Speed Handpiece is an LED, push-button air turbine handpiece that attaches to NSK-style quick-connect couplers. It is a GoldGreen Dental handpiece, not an NSK-brand product. Every GoldGreen Dental handpiece comes with a 12-month limited manufacturer warranty. If it fails from a defect in materials or workmanship, we replace it.

The built-in LED light helps improve visibility inside the oral cavity, and the push-button quick-release chuck allows fast bur changes during treatment.

Coupler not included. If your unit doesn't already have one, add the NSK-compatible LED quick-connect coupler ($219).

Instructions for Use:

Please follow the instructions below to ensure optimal performance, longevity, and patient safety.

Pre-Use Setup

Before use, inspect the handpiece and confirm that it is functioning properly. Do not use the handpiece if it appears damaged, loose, abnormal, or unsafe.

Operate the handpiece at the recommended working pressure of 25–30 PSI. Avoid excessive air pressure, as improper pressure may affect performance or damage the turbine cartridge.

Use only ISO-standard burs with an approximate bur size of 1.59–1.60 mm. Do not use bent, damaged, or non-concentric burs. Always make sure the bur is fully seated and securely locked before operating the handpiece.

Allow the bur to stop rotating completely before removing or replacing it.

Post-Use Maintenance

• Cleaning:
  • Disconnect from the tubing.
  • Wipe external surfaces with an approved disinfectant wipe.
  • Do not immerse in water or ultrasonic cleaner.
• Lubrication:
  • Apply handpiece lubricant via the drive air tube (as per lubricant manufacturer’s instructions).
  • Run the handpiece for 20–30 seconds to expel excess oil.
• Sterilization:
  • Autoclavable at 134°C (273°F); autoclave for 3–5 minutes.
  • Allow to cool fully before next use.

4. Safety & Warnings

• For professional dental use only.
• Never operate the handpiece without a securely installed bur.
• Do not exceed recommended pressure or speed specifications.
• Regularly inspect bearings and turbine for wear to maintain performance.
• Use only compatible burs and maintain proper sterilization protocols.
