Heat shrinking toolholder
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 version 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.

Advantages – Your benefits

  • High clamping forces
    Secure and friction-locked clamping for transmission of high torques
  • Good ratio between radial rigidity and interfering contour
    High machine-cutting performance and quicker machining times for increased productivity
  • Toolholder for powerful metal cutting
    High-speed machining of machine speeds up to 50,000 RPM and for use of HSS and HM tools
  • Run-out accuracy ≤ 0.003 mm measured according to DIN 69882-8 in the clamping bore
    Optimal surface results, high precision machining and safe processes due to a uniform cutting action and highest repeatability
  • Universally applicable
    Suitable for use in milling, finish milling, drilling or HSC machining
  • Dynamic form
    With long chucks, the reinforced shank offers an effective compromise between slimness and sturdiness
  • High level of flexibility
    Can be ideally combined with CELSIO SVL heat shrinking extensions
