Description
Version:
External and internal tapers are ground. All shanks are hard turned for smooth running. Including RFID/Balluffchip bore, high-performance clamping nut up to 25000 rpm.
Advantage:
- 3 µm radial run-out with a 2 µm clamping nut, 6 µm radial run-out with a 5 µm clamping nut.
- Extremely strong holding force (up to factor 2better than the standard ER chuck).
- Vibration reduction effect due to 2-part clamping nut (size 11M and 16M 1-piece).
Application:
For clamping tools with plain shank in collets to DIN 6499 - Form A and B.
Supplied with:
Precision clamping nut.
