Duoplug®

Optimal stability with maximum concentricity

The Pokolm Duoplug® system offers optimum stability with maximum concentricity. Compared to conventional screw-in tools, the holding forces between the tool and the holding system are spread over the entire surface of the shrink fit as well as large parts of the thread.

The shrink connection offers an absolutely backlash-free fit and, in combination with the screw-in system, ensures maximum concentricity and rigidity – just right for deep contours.

The significantly increased holding forces compared to conventional screw-in systems enable a precise and reproducible tool fit. For long overhangs, the simultaneous form and force fit between the holder and the milling cutter also helps to achieve a high surface quality.

The high tensile strength and thermal stability of Duoplug® is achieved through the use of special materials with a special hard coating.

Ideal areas of application are finishing and roughing operations with long overhangs, high-feed milling in deep contours, and high-precision finishing operations. As an extremely slim holder system, Duoplug® is also suitable for deep machining situations on vertical walls.
