Air-actuated high-speed collet chuck for repeat clamping of round workpieces.
High-Speed Pneumatic Collet Chuck
KORRETTO high-speed pneumatic collet chuck uses compressed air for clamping and release in collet-style workholding. It is suitable for round parts, shafts and sleeves where fast actuation, compact structure and repeat clamping are required. This page is for a collet chuck product, not a general pneumatic jaw chuck or BK-series pneumatic chuck.
Product Overview
The high-speed pneumatic collet chuck is used where a round workpiece needs fast air-actuated collet clamping. Compared with a jaw chuck, a collet chuck provides more uniform contact around the clamping diameter. Compared with hydraulic systems, pneumatic actuation can be simpler for light to medium clamping loads.
JAW High-Speed Pneumatic Collet Chuck is listed as a separate series with its own drawing and parameter table. Select between the two according to the model, clamping range, actuator layout and required speed.
Key Features
| Feature | Description |
|---|---|
| Pneumatic actuation | Uses compressed air for clamping and release. |
| High-speed collet workholding | Suitable for rotary applications requiring speed and repeatability. |
| Uniform round-part contact | Collet clamping supports round shafts, sleeves and small precision parts. |
| Compact structure | Useful where a standard chuck is too large or heavy. |
| Different from BK pneumatic chucks | This is a collet chuck page, not a pneumatic jaw chuck page. |
Typical Applications
- Round workpieces
- Shaft and sleeve clamping
- High-speed rotary clamping
- Light to medium cutting conditions
- Repeat pneumatic collet workholding

FAQ
What is a high-speed pneumatic collet chuck used for?
It is used for air-actuated collet clamping of round workpieces where quick clamping, release and high-speed rotation are required.
Is this a general pneumatic chuck?
No. This is a pneumatic collet chuck. It uses collet-style clamping rather than standard jaw clamping.
How is this different from the JAW High-Speed Pneumatic Collet Chuck series?
The JAW series has its own drawing and parameter table. Select according to the model, clamping range, actuator layout, required speed and machine interface.
What should be checked before selection?
Check the workpiece diameter, collet type, air pressure, speed, clamping force, spindle interface and cutting load.
Can this chuck replace a hydraulic collet chuck?
It depends on required clamping force, speed, cycle time and machine layout. Pneumatic and hydraulic actuation should be selected according to the process.
