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.

Set-up in seconds
TENDO is fine-balanced by default (G2.5 / 25,000 RPM)
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 process-reliable and precise clamping device with standardized outside contour according to DIN 69882-7.
The TENDO E compact hydraulic expansion toolholder convinces when milling, drilling, reaming, thread machining and in HPC applications And all that with an up to 300% longer tool service life. The Dual Contact variant 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 service life, high flexibility as well as Plug & Work while it can even be used with minimal quantity lubrication. The TENDO Slim 4ax Cool Flow variant enables peripheral cooling through 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 standard machine tool spindles. With standardized outside contour according to DIN 69882-7.
The TENDO Zero hydraulic expansion toolholder is the pro for tight tolerances when reaming, fine-drilling and finish boring – or wherever perfect run-out accuracy is essential. This enables even minimal run-out errors with tools, mountings, and the machine spindles to be individually compensated.
TENDO ES with zero interfering contour is used, when every millimeter in the machine room counts. The extremely short hydraulic expansion toolholder from SCHUNK is perfectly suitable for machining large workpieces – even in confined spaces in the machine room – and deep-hole drillings.
TENDO LSS negotiates the obstacles posed even by trickiest of tasks, when machining at the narrowest of angles and where workpieces are hard to reach. Thanks to the high stability and the radial stiffness offered, the super-slim toolholder is ideally suited to boring, countersinking, chamfering, and for finish milling machining operations.
When the sensitive set of gears is oriented, this set-up time minimizer gives you micron-precise positioning for the tool length. The length adjustment screw is equipped with a front and back stop.
In addition to the highlights such as the versatile clamping range due to the use of intermediate sleeves, the run-out and repeat accuracy of < 0.003 mm (DSE double clamping insert), and the easy handling, TENDO Turn particularly convinces by its unique vibration damping. This helps you to realize excellent workpiece surfaces.
The iTENDO² is an intelligent toolholder, available in three variants, which uses an acceleration sensor close to the workpiece to provide precise stability values for process optimization. The basic version of iTENDO² Pad sends data wirelessly to a tablet PC. iTENDO² easy connect enables integration into the machine with data transmission to a process monitoring system via an analog interface. The iTENDO² easy monitor version offers a software extension for easy process monitoring with machine integration.
