Tool Clamping - Introducing PGR "powRgrip®" clamping system.
The clamping system PGR “powRgrip®” is a mechanical alternative to thermal shrink-fit and hydro-expansion chucks, and is suitable for the clamping of both solid carbide and HSS tools.
As opposed to shrink-fit technology, there are no heat-related structural changes on the tool holder.
The PGR system permits safe clamping in tolerance h9 (type PGR-GB) or h6 (type PGR) and shows extraordinary performance in the enormous torques it can transfer, as well as in its excellent concentricity characteristics.
A special feature for pre-setting the tool is integrated in each collet.
