Use Techniks DualDRIVE holders if your machine has a dual-contact spindle. 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. Dual-contact increases rigidity and accuracy during machining.
All Techniks end mill holder bores are manufactured to meet or exceed the H5 specification. H5 is an extremely accurate bore I.D. and provides improved T.I.R. for extended cutting tool life.
Please specify your bore I.D. (shank size) when ordering replacement lock screws to ensure correct replacement.
