Integrated Handpieces: Ergonomic, Functional, Reliable


The extra slim head and body design of the NSK FX25 1:1 Push Button Latch vastly improves visibility in the operational field, even in difficult-to-access areas. Cartridges are designed to be easily replaced during surgery with accessory tools supplied with the new product. Costs for service and downtime are reduced. (FX25/FX25m/FX23)

Clean Head System

The NSK FX25 1:1 Push Button Latch features the patented NSK Clean Head System with a special mechanism to prevent oral fluids and other contaminants from entering the handpiece head, thus prolonging the life of the bearings.

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.

High Precision Gears

The high-precision gears run quiet and are supremely durable, which also reduces uncomfortable vibration.
