Dual-Contact Spindles
Dual-Contact is a spindle option offered by some machine tool builders. Dual-contact means both the toolholder taper and the flange make contact with the spindle. The dual-contact provides increased rigidity and accuracy during machining.
Use Techniks DualDRIVE holders if your machine has a dual-contact spindle.
