SB240 | Rubber-Flex Expanding Collet for Blind Holes
The TOP-TOOL SB240 Rubber-Flex Expanding Collet for Blind Holes is used for internal expansion clamping where the workpiece bore does not pass fully through.
This rubber-flex expanding collet is selected according to bore size, clamping range and available internal locating surface.
Key Features
- Rubber-flex clamping provides broad contact around the workpiece.
- Suitable for workpieces requiring stable, repeatable and surface-sensitive clamping.
- Different series support through-hole, blind-hole, inner-stop, expanding, air-operated, accessory and multi-spindle applications.
- Model selection is based on clamping range, chuck size, mounting method and repeatability requirement.
Typical Applications
- Round, square or hexagonal workpieces
- Thin-wall or surface-sensitive parts
- Workpieces requiring broad contact clamping
- Repeat CNC workholding applications
- Applications where jaw marks or point contact should be reduced
- Rubber-flex collet setup, changeover or preparation workflows where applicable
Selection Notes
- Confirm the workpiece shape and clamping diameter.
- Check whether the application requires through-hole, blind-hole, inner-stop, expanding, air-operated or multi-spindle clamping.
- Review clamping range, mounting method and repeatability.
- Confirm whether a chuck assembly, replaceable rubber-flex collet element or supporting tool is required.
- Send the workpiece drawing and machine information for technical review before ordering.
