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)
