- Type: Collet clamping nut (ER20 series)
- Load: Clamping force applied radially around the collet to secure cutting tools
- Cage: Not applicable; uses threaded clamping mechanism with collet interface
- Performance: Provides firm tool holding, consistent clamping pressure, and stable machining performance
- Construction: Threaded nut body designed to engage with ER20 collet and compatible tool holder
- Use cases: CNC milling, engraving, drilling operations, router spindles, machining centers
- Note: Must be used with ER20 collets and compatible holders; correct tightening torque and clean surfaces help maintain accuracy and reduce runout.
