New side lock chucks for cylindrical shanks with HB clamping surface

In many production facilities, Weldon tool holders are used as the standard chuck for solid carbide milling cutters. However, the design of this type of chuck limits its application. Indeed, the tolerances of the fit for the tool adapter are high (at a clamping diameter of 20 mm, the maximum clearance is already 22 µm). This results in a large run-out error that causes imbalance, as well as wear on one side of the tool, creating adverse effects on machining quality.
