Technology & Function

  • DYNAMIC POWER SYSTEM
    DYNAMIC POWER SYSTEM

    Equipped with the new "DYNAMIC POWER SYSTEM", the handpieces provide revolutionary power. The enlarged exhaust port, optimized nozzle structure, and enlarged rotor bucket achieve the highest rotational power in its category*.

    *Power compared with the same handpiece class offered by other major manufacturers (as of July 2023)

  • DURAPOWER CHUCK
    DURAPOWER CHUCK

    Equipped with "DURAPOWER CHUCK", a new chuck* that provides a more sustained gripping force that reduces the risk of bur slippage compared to conventional models.

    *The chuck is the part of the handpiece that holds the bur (cutting rod). The new improved chuck mechanism has improved durability.

  • Quick Stop Function
    Quick Stop Function

    The Quick Stop Function stops high speed rotation in around 1 second. It improves safety in the oral cavity by halting drill spin. The result is efficient, high speed cutting and incredibly safe surgeries.

  • Easily replaceable cartridge
    Easily replaceable cartridge

    The cartridge can be easily replaced by the user, eliminating time lost from sending the handpiece in for repair and ensuring a consistently good treatment environment.

  • 100° angled head
    100° angled head

    Considering the physiological curves of the oral cavity (Curve of Spee and Curve of Wilson), the 100° angled head enables easier access and high-torque cutting for efficient treatment in the oral cavity.

  • DURAGRIP coating
    DURAGRIP coating

    The surface of the pure titanium body is blasted to eliminate shiny surfaces by producing micro surface unevenness, and then coated in our original “DURAGRIP” coating. As well as improved scratch resistance and durability, the uneven surface ensures a comfortable, non-slip grip.

  • Microfilter

    Equipped with built-in water filter. The 0.3 mm diameter mesh water filter prevents foreign matter from entering the water line, reducing problems of clogging.

Testmonials

  • Dr. Ron Kaminer, DDS FAGD The Z890 and Z990 high speed air driven handpieces are a total game changer. Weightless in the hand, clear directed water spray and decibels lower than most high speeds, these are a must for every practice!

  • Dr. Joyce Bassett, FAACD, FAGD Love my NSK Z990L air-driven handpiece! It is light and I can prep teeth and contour restorations effortlessly. The head is so small I can get the handpiece into the back of the mouth even with a limited mouth opening - I just love it!

  • Dr. Foroud Hakim, DDS I always say to colleagues, "It's hard to practice to our fullest potential without electric handpieces." NSK has proven me wrong with their latest air driven handpieces, the Z990 & Z890! Without sacrificing power and efficiency, they provide the feather touch control that fans of air driven turbines crave, but that's just the tip of the iceberg.
    Top notch illumination, perfect water mist, and acoustics that are kind to both patient's and doctor's ears, this line is a marvel of engineering and design!
