About Spindles

We offer different type of spindles for the rotor.

NSK Type Spindles:  （Recommand for most of the clients)

Build with a strong spring and chuck inside the spindle, the chuck hold the bur (bur diameter 1.595mm) with 2.25-2.75KG grip power. The chuck will hold the bur tighter when there is pressure on the bur, the more pressure, the tighter it hold.

Advantage: Lub Free and more durable! It will always keep working even there is no lubrication on the spindle.

Disavantage: It didn't hold the bur as hard as the kavo model in the beginning. We need to explain to the dentists if they are not familiar with this kind of spindle before.

Kavo Type Spindles: (Most of the European dentist like this kind of Spindle)

Build with strong chuck, holding the bur with more than 4.5KG all the time.

Advantage: Hold the bur tighter all the time.

Disadvantage: The chuck may have problem if the client didn't lubricate the chuck.
