NSK Presto Chuck


Replacement chuck for the NSK Presto Cartridge. When the chuck wears out, your cartridge will no longer hold onto the burs tight and the burs may come out of the cartridge during operation.


NSK Presto Chuck for the NSK Presto Cartridge.

When using friction grip dental burs, it is not uncommon to wear out a chuck over time. Chucks are wearable parts that simply will wear out over time as bits are inserted, then removed from the chuck. When your chuck wears out, your cartridge will no longer hold the burs tight and the burs could come out while the handpiece is running. (not good!)

As sure way to tell when your chuck needs replacing is when you press the bur in and you don’t hear a distinctive “CLICK”.

You must hear the “CLICK” in order for the bur to be seated properly in the chuck. If you don’t hear the “CLICK” and you press too hard, you will damage the shaft and need to replace the cartridge.

Save money over replacing the entire NSK Presto Cartridge by replacing only the chuck.



NSK recommends removing the chuck from the cartridge for cleaning and light lubrication on a monthly basis. If you clean and lubricate the chuck monthly and use only high quality burs, your chuck will last a very long time.  (Due to the variation in burs and other factors, chucks do not come with a warranty from NSK or Utah Handpiece Repairs. Please follow all recommendations)
