Designed for use with dual-contact spindle systems, Taper-Face Toolholders provide 2 surfaces of contact for optimized rigidity and consistency. Products use plastic deformation of machine spindle to achieve simultaneous fit of both taper and flange face from holder to create rigid connection and prevent toolholder from being pulled into machine spindle. Toolholders are available for BT30 TF, BT40 TF, BT50 TF, CAT40 TF, and CAT50 TF spindle connections, in both inch and metric programs.
