MR 16 – MR 32

Quiet machining

The grooveless micRun Hi-Q clamping nuts lower noise levels.

Cooling available

Achieve internal cooling with our sealing disks or peripheral cooling with our coolant flush disks.


Optimal balancing for high-speed applications.


Higher transferable torque

Lower frictional forces resulting in up to 80 % higher gripping force over standard nontreated clamping nuts.

Collet-locking system (pat. pend.)

Retains collet in nut for easier assembly. Further, no tool is needed to remove the collet.

Strongest clamping

A fine thread instead of a ball bearing together with a low friction design make our micRun Hi-Q clamping nuts one of the best high-precision clamping nuts on the market.
