Description
Version:
All shanks hard turned (for smooth running!).
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 side flats to DIN 1835 B and DIN 6535 HB.
