Autochucks & Sub-assemblies
About Dental Handpiece Autochucks
Autochuck is another name for the push button spindle/chuck (collet) assembly which holds the dental bur and onto which the other components of the turbine cartridge (e.g. bearings, impeller) are attached or pressed. The ISO maximum specification for concentricity (run-out) is 0.0012 in. / 0.03 mm.
Two common autochuck designs are clamp-pad and wedge.
Extend dental sub-assemblies are designed to meet or exceed the OEM specifications for handpiece turbines. They offer premium features and an extended warranty for high speed turbine repairs.
- Optimized wedge angle = easier actuation
- Tighter tolerance on the bur guide bushing and collet = improved concentricity and longevity
- Carbide or a clamp pad design
- Improved heat treat specifications
- 100% precision laser balanced
- 15 month No Hassle Warranty
- Some custom configurations for individual models
