Description

Version:

All shanks hard turned (for smooth running!). With RFID/Balluffchip bore and cooling channel bores.

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
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.

Supplied with:

Lock screw.

Optional extras:

Pull studs (PS) No. 308760308806. Special toggle spanner No. 309840.
