Toolholder Extensions


The slim design of the TRIBOS-SVL toolholder extensions allows precise and smooth machining of workpiece areas that are difficult to access. In spite of the slim design, the extension is robust and permits a run-out accuracy of less than 0.003 mm. The TRIBOS-SVL can be combined with a  variety of toolholders, such as our TENDO hydraulic expansion toolholders, CELSIO heat shrink toolholders, with collet toolholders, and of course with TRIBOS tool holders. 

The TRIBOS extensions in connection with our TENDO hydraulic expansion toolholders or the TRIBOS-R polygonal toolholders complement each other in an ideal manner. Both systems have a vibration damping effect on the overall system. The TRIBOS SVL has a wide range of clamping diameters. They are available in metric from 0.3-20 mm and in inches from 1/8- 3/4 inch.
