Description
Version:
- High-temperature steel.
- Integral tool length adjustment, adjustment track 10 mm.
- Suitable for shrink fitting of HSS and carbide tools.
- All shanks hard turned (for smooth running!).
- With RFID/Balluffchip bore.
Advantage:
The double contact between the taper and the flat flange creates a more stable and precise clamping situation:
- Better surface quality
- Longer tool life times
- Consistent seating in the headstock (even at high speeds)
- Smaller radial run-out
Application:
For clamping tools with parallel shank to h6 tolerance.
Standard:
Similar to E-DIN 69882-8, form G.
