30 years of service for our powerful all-rounder: Happy Birthday HSK gripper!


From very small to very large, from fine machining to heavy-duty cutting – our HSK grippers are true all-round solutions at the interface between tool and machine. Since their birth, they have formed the base for the safe and reliable clamping of hollow taper shank tools. Installed in countless applications all over the world, they set exclamation marks in terms of user friendliness, productivity and size with every further development.

We would like to thank all our customers for their decades of loyalty and the constant new technical challenges. Join us on a journey through time to the various development stages of our HSK grippers. Let yourself be inspired by a real success story and be curious about the following milestones.

  • today

    High product diversity for our customers: With changing market and customer requirements, new products are constantly being created and extending our HSK gripper family – and this has been the case for 30 years now.

  • 2017

    Small but powerful: Miniature grippers for interfaces smaller HSK-E 20 expand the manufacturing possibilities in watch, jewellery and medical technology. In the production of microtechnical components, they ensure greater efficiency and energy savings.

  • 2015

    Create space where it is needed: Our powerful HSK grippers enable the realisation of extremely compact complete clamping systems for even greater degrees of freedom in the machine room.

  • 2013

    For shorter spindle lengths: Our designers develop force-amplifying HSK 63 grippers in compact design. The length advantage is over 30 % compared to the standard, without any loss of performance.

  • 2006

    The professional in heavy-duty cutting: At customer’s request, a force-amplifying HSK 100 gripper with 75 kN maximum clamping force is created. The main field of application is heavy-duty cutting, e. g. the machining of turbine blades for the aerospace industry.

  • 2000

    Change of times: The second generation of our force-amplifying HSK grippers sets standards on the market. The design principle and the surface coating make force amplification factors greater than 5 possible. The optional holding function ensures even faster tool change times.

  • 1997

    Robust power pack: Our gripper with direct force transmission and short stroke for long-lived tool clamping systems is extremely durable. It can transmit clamping forces that far exceed the values specified in the HSK standard.

  • 1993

    Hour of birth: The first BERG gripper for hollow taper shanks is delivered. The integrated wedge gear multiplies the actuation force by a factor greater than 3. It is available in two versions and can thus be used for wet and dry machining.
