CELSIO is a heat-shrinking system that is suitable for different shrinking devices. It uses induction heat from eddy currents to heat the heat shrinking toolholder, which clamps the tool shank firmly. The unit of toolholder and tool forms an almost homogeneous connection. The Cool Flow variant of the CELSIO toolholder has integrated cooling channels that can be closed with M3 screws to direct the coolant directly to the cutting edge of the tool. The Dual Contact version offers a simultaneous taper and flat work surface for machines with a corresponding interface, closing the gap between the tool flange and the spindle face.
