    S-Max M Series

    Toughness

    The S-Max M series contra-angles have dramatically improved durability, and feature an updated internal body design and chuck mechanism.
    They are NSK's next-generation standard - a marriage of ergonomic sophistication and smooth cutting feel.
    Experience them for yourself.

    Technology & Function

    Ceramic Bearings

    Ceramic Bearings

    The ceramic bearings are 25% harder than steel and around half the weight, meaning very little wear, which helps the cartridge to last longer.

    Clean Head System

    Clean Head System

    The Clean Head System has an anti-suck back mechanism that stops blood and foreign matter from entering the head from the oral cavity. As a result, the ball bearings and mechanical parts last longer.

    Quattro Spray

    Quattro Spray

    Sprays more effectively over the entire bur for better cooling. (M95L / M95 only)

    Slimmer Shape

    Slimmer Shape

    The grip has been made slimmer in response to requests for a design that avoids contact with the front teeth when accessing molars.

    Push Button Chuck

    Push Button Chuck

    Push Button Chuck is NSK's original push button auto-chuck mechanism that tensions the bur grip during rotation. It allows one-touch bur insertion and removal without tools. The bur lock mechanism is designed so that bur retention strength increases when high loads are applied to the bur.

    Single Water Spray

    Single Water Spray

    The NSK Single Water Spray effectively cools the surface of the bur with a high cooling effect. (With M65)

    Double Sealing System

    Double Sealing System

    NSK's original double sealing system reliably prevents blood and bodily fluids from entering the instrument head. This guarantees longevity of the instruments. (With SG20)
