The most durable hydraulic expansion toolholder on the market
TENDO has been a synonym for highly precise shank tool clamping for many decades. With its continual developments, this forward-looking clamping technology meets the constantly increasing requirements of demanding, universal precision machining. TENDO is suitable for all common shank types. The large selection of products ensures that the right solution for almost any application can be found. TENDO masters any challenge - whether it's short or long, thick, slim and interfering contour optimized, for milling, tool grinding or turning machines. Intermediate sleeves make versatile clamping ranges possible.

TENDO Silver provides a budget-friendly entry into the world of hydraulic expansion technology, offering the best price/performance ratio in direct clamping. Nine interfaces make the TENDO Silver a precise clamping device with a reliable process that is compatible with all machine tool spindles.
With our new iTENDO² we have taken the idea of intelligent toolholders to the next level. It is available in three different packages to make switching to this technology even easier. One common element in all of them is the iTENDO² toolholder, which, due to its closest-to-the-part acceleration sensor, provides precise stability values that can be used to optimize the machining processes. As a tool to increase your process transparency, the basic version of the toolholder can send the captured data directly to the tablet supplied. With the variant "easy connect", the measured values can be transferred to other systems via an analog interface. In the variant "pro", which will be available in the future, it will also be possible to send the data directly to the machine control system. All variants are upward compatible, i.e. you can use the tablet PC variant to start testing the technology. Once you are convinced of the benefits of an intelligent toolholder, it is easy to switch to the more extensive packages for monitoring and optimizing your processes automatically.
The TENDO E compact hydraulic expansion toolholder convinces when it comes to milling, drilling, reaming or thread machining. And all that with an up to 300% longer tool service life. This is evidenced by a study conducted by the wbk Institute of Production Science at the Karlsruhe Institute of Technology (KIT).
The TENDO E compact hydraulic expansion toolholder with simultaneous taper and flat work surface closes the interface-related gap between tool flange and the front of the machine spindle with the interface of the flat work surface.
The SCHUNK TENDO Slim 4ax is a toolholder for axial machining and radial fine machining. It is the only one in its class to meet all requirements: Heat-shrinking contour according to DIN 69882-8, easy handling, short set-up times, long tool life, high flexibility as well as Plug & Work while it can even be used with minimal quantity lubrication.
The SCHUNK TENDO Slim 4ax Cool Flow is the toolholder for axial machining, which is the only one in its class to fulfill all requirements. Heat shrinking contour as per DIN 69882-8, simple handling, short set-up times, long tool service life, high flexibility, as well as Plug & Work, and suitable for the use in applications with minimum quantity lubrication. The TENDO Slim 4ax Cool Flow enables peripheral cooling using cooling channels in the wall. The coolant is fed directly to the cutting edge of the tool.
TENDO “The original” is the hydraulic expansion toolholder from SCHUNK. The extensive range of 29 interfaces makes the TENDO toolholder a precision all-rounder that is compatible with all machine tool spindles.
The TENDO Zero hydraulic expansion toolholder is the professional toolholder for tight tolerances for boring, reaming, and finish boring – wherever perfect run-out accuracy is a must. This enables even minimal run-out errors with tools, mountings, and the machine spindles to be individually compensated.
TENDO LSS negotiates the obstacles posed even by trickiest of tasks, when machining at the narrowest of angles and where workpieces are difficult to access. Due to the high stability and high radial rigidity, the super-slim toolholder is ideally suitable for boring, reaming, and finish milling machining operations.
TENDO ES, with zero interfering contour is used, when every centimeter in the machine room counts. The extremely short hydraulic expansion toolholder from SCHUNK is perfectly suitable for machining large work pieces – even in confined spaces in the machine room – and for deep-hole drilling.
In addition to highlights such as the versatile clamping range by using intermediate sleeves, the run-out and repeat accuracy of < 0.003 mm (DSE double clamping insert), and the easy handling, TENDO Turn particularly impresses by its unique vibration damping. This helps you to realize excellent workpiece surfaces.
