      Description

      Version:

      External and internal tapers are ground. All shanks are hard turned for a smooth cutting action. Including Balluffchip bore, high-performance clamping nut up to 25000 rpm.

      Advantage:

      • Excellent concentricity in the system (chuck + collet + clamping nut), 3µm radial run-out with a 2µm collet, 6µm radial run-out with a 5µm collet.
      • Extremely strong holding force (up to factor 2 better than the standard ER chuck).
      • Vibration reduction effect due to 2-part clamping nut.

      Application:

      For clamping tools with plain shank in collets to DIN 6499 - Form A and B.

      Supplied with:

      Precision clamping nut.

      Optional extras:

      Coolant pipe No. 309880, Coolant pipe plug-in socket No. 309890, ER clamping wrenches No. 309748 / 309749 Fahrion brand ER collets 308901 − 309434.

      Note:

      • Clamps only nominal ⌀ up to shank ⌀ tolerance h 10.
      • Do not use the clamping nut in combination with a sealing washer.
