Handpiece chucking difference
Publish Time: 2019-10-11 Origin: Site
What are the Different Types of Chucking Mechanisms?
1. Standard Screw-Type (bur tool-type)
The spindle and chuck (the parts of the turbine that hold the bur) are separate.
A bur tool is required to insert and remove the bur; it screws the chuck down into the spindle causing the chuck to tighten around the bur.
Screw-type chucks can be replaced in repair.

2. Push Button-Type
The spindle and chuck are a single assembly.
The push button cap on the handpiece presses on the actuator on the top of the spindle which engages an internal spring component to open or close the chucking mechanism.
Bur shank size is important – burs with shanks under .0626 or over .0630 cannot be used.
