- Used for most internal workholding applications
- Most economical
- Pull back clamping action
- For parts with longer bores or stepped internal diameters.
- Collets tend to conform to slightly tapered bores.
- Ideal for gripping in blind bores.
- Pull back action for positive location
- Used for internal workholding of parts with longer bores.
- Higher grip force compared to single and double taper arbors.
- Longer collet length allows for more expansion.
- Pull back action for length control.
- Used for when high gripping forces are required.
- Great for automated load, positive clamp/unclamp
- Air sensing capable
- Pull back action
- Ideally suited for grinding, turning, and inspection operations that require locating between machine centers.
- The extended arbor body is knurled to make handling easy and is arranged with a flat for mounting a drive dog.
