- Precision ≥ 0,005 mm/0,0002” inch
- Recommended for high speed RPM where great machining precision is required
- Nominal diameter
- To be used on all types of toolholders and standard nuts

Klein® ULTRA PRECISION ER 16 spring collets are recommended for very accurate and high speed machining on CNC machining centers and router machines.
Thanks to their concentricity tolerance within 0,005mm/0.0002’’ (runout of 5 micron), they are able to guarantee a higher precision of coupling with the tool and to minimize the unbalance with the tool holder.

The advantages of ULTRA PRECISION Klein® spring collets:
- higher precision (runout of 5 microns)
- excellent performance when working at high RPM
- vibrations reduced to a minimum (for the protection of the electrospindle)
- recommended in large scale productions
- can be used on all standard tool holders and nuts
