Polygonal Extensions
The use of TRIBOS SVL extensions makes it possible to use standard cutting tools instead of expensive special tools. The extension with a run-out accuracy of < 0.003 mm and slim interfering contours can be used in combination with various SCHUNK toolholders. The TRIBOS SVL extensions ideally complement each other in connection with the TENDO hydraulic expansion toolholders or the TRIBOS-R polygonal toolholders. Available in two versions: coolant-proof up to 120 bar or with peripheral cooling.
