Polygonal toolholders
With its unique polygonal honeycomb structure and increased outer diameter, TRIBOS-R offers an optimum ratio between radial rigidity and dampening, and provides the best dynamic run-out properties.

Advantages – Your benefits

  • Maximum radial rigidity
    Optimal running smoothness and excellent shape and positional tolerances on the workpiece
  • Excellent vibration damping
    No lateral deflection during the metal cutting process and stabilization of the entire system: Spindle – toolholder –cutting tool
  • Comprehensive compatibility
    Can be ideally combined with TENDO SVL and TRIBOS SVL extensions
  • Best dynamic run-out properties
    Best results for shape accuracy, surface quality, and shape and positional tolerance
  • All commercially available tool shank types can be clamped
    Form A: with smooth cylindrical shank, shank form A in accordance with DIN 1835 and DIN 6535 HA Form AB: with flat face and cylindrical shank with pulling face, shank form B in accordance with DIN 1835 and DIN 6535 HB Form B: with lateral pulling faces, shank form B in accordance with DIN 1835 Form E: with inclined clamping face, shank form E in accordance with DIN 1835 and DIN 6535 HE
  • Axial length adjustment
    Length adjustment in the range of 0.01 mm accuracy, with adjustment travel of 10 mm
  • Fine-balanced by default
    Suitable for high speeds with a balancing grade of G2.5 at 25,000 RPM
  • High level of flexibility
    Clamping of different diameters due to the use of slotted or coolant-proof intermediate sleeves
