    The company was founded in 1945 by Friedrich Schunk as a mechanical workshop, and has developed under the leadership of his son, Heinz-Dieter Schunk,

    Detailed Specification

    The TENDO E compact hydraulic expansion toolholder convinces when milling (volume cutting, finishing), drilling, reaming, and 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). And this applies for every tool brand.

    Field of application

    For volume machining, reaming, drilling, counterbore/chamfering and thread tapping


    Highest torques

    Now up to 2,000 Nm (with Ø 32 mm) and 900 Nm (with Ø 20 mm) under dry clamping conditions, 900 Nm (with Ø 32 mm) and 520 Nm (with Ø 20 mm) with oily tool shanks.

    Permanent run-out and repeat accuracy of < 0.003 mm

    Optimum surface results, high precision processing and safe processes due to uniform cutting action and highest reproducibility.

    Micron precise tool change in seconds without peripheral equipment

    Time saving through reduction of set-up time and no investment and energy costs due to additional clamping devices

    Fine-balanced by default

    Suitable for high speeds with a balancing grade of G2.5 at 25,000 rpm.

    The torque monster

    Up to 60% higher torques compared with commercially available hydraulic expansion toolholders

    The precision guarantor

    More than 70% better run-out than ER collet chucks due to a high radial rigidity

    The endurance runner

    Up to 40% larger volume cutting is possible before the tool has to be reground

    The perfectionist

    100% reproducible tool change of < 0.003 mm

    The more intelligent

    Up to 40% longer service life due to the oil-shock absorber-effect

    Amazingly simple and efficient

    Up to 80% faster tool change

    The price advantage

    Up to 65% savings of the procurement costs!
