Flexible length pre-setting possible through movable intermediate piece.
With cooling channel slots.
Flexible length pre-setting possible through movable intermediate piece.
With cooling channel slots.
Application:
- For drilling, reaming, milling, and tool sharpening.
- Very high flexibility due to reduction in clamping diameter.
- Very high torque guarantees a higher volume of metal removal compared to direct clamping.
- Concentricity ± 5 µm (system accuracy at 3×D).
- Concentricity ± 2 µm (for reducing adapter).
- Can be used in all commercially available hydraulic chucks.
Suitable for:
Hydraulic chuck with clamping ⌀ 20 mm.
