Tool holders or Inserts holder with a VDI shank or shank with a cross seat are often used on CNC lathes with a Revolver head. The cross seat refers to the orthogonal positioning of the toolholder seat with respect to the VDI shank. VDI shanks are mainly divided into four families VDI30, VDI40, VDI50, VDI60, depending on the size of the revolver head. The clamping system is achieved by means of a guide diameter and a modular rack on the tool holder, which uses a toothed wedge to secure the tool holder or holder to the revolver head. Tool holders are available in different lengths according to the dimensions. In addition, for each size or VDI shank, tool holders are available in toolholder sizes 16x16, 20x20, 25x25mm.
