Techniks’ DualDrive toolholders, which can be used with all spindles, eliminate the gap between the toolholder flange and the spindle face to provide increased rigidity and accuracy when cutting. The company recommends using these toolholders when high metal removal rates, high feed rates and/or machining at extended lengths is desired. The toolholders are offered in versions including ER collet chucks, end mill holders, shrink-fit holders and shell mill arbors. Flange kits are available to adapt the toolholder to fit standard spindles. Those kits are not required for dual-contact spindles.
