- 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 Balluffchip bore.
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
A BT double contact arbor can also be used in a standard BT machine spindle – and vice versa. The advantages of the double contact are however achieved only when a double contact arbor and double contact spindle are used together.
For clamping tools with parallel shank to h6 tolerance.
