Description
Information:
- Holder for mounting ER40 collet chucks.
- Tapered ISO shank according to DIN2080 ended with a thread for pulling in conventional machines.
- A correctly seated collet is perfectly flush with the face of the ER nut, only then should we tighten the whole thing with a special hook wrench or multipoint.
- Correct seating in the spindle ensures self-locking counterforce when tightening and loosening the tool.
- Standard collets have a round hole, which makes the holder universal, as we can clamp all shank tools with a cylindrical shank or cylindrical shank with a Weldon flattening, i.e. drills, or mills.
- Through-through tool for internal cooling.

How to properly mount a collet in an ER nut?
The collet should be mounted at an angle by hooking the cage channel onto the eccentric or cylindrical nut clamp (A), feeling a slight resistance, press until a characteristic "click" is heard (B). Disassembly is equally simple, tilt the cage to release it from the clamp in the nut (C).
