chucks. carrier blocks also engage in the slots at the shank end.
Advantages vis-à-vis steep taper:  Ideal for high rotation speeds: at high rotation speeds the spindle expands
 High rigidity: considerably greater bending strength is achieved with the same due to centrifugal force. This could cause the steep taper to slip in the spindle
and jam. This is prevented by the fl ange. In addition, the clamping elements are
tool sizes as a result of the support at the collar (fl ange). pushed outwards by centrifugal force which increases the clamping force.
 Excellent change precision: the fl ange attachment facilitates axial positioning  Integrated tool system: the hollow shank taper was designed for both stationary
precision in the µm range. The form-fi t, tight taper tolerance prevents any and rotating tool chucks. This enables the tool holders to be used on milling
radial run-out. machines and lathes and as modular tools.
