Collet ER40
The ER40 collet is a removable clamping device inserted into a collet chuck with an internal diameter of 40 mm and fixed in it with a clamping nut. Such equipment is used in drilling, milling and other machines and machining centers for reliable clamping of the cylindrical shank of an axial cutting tool. ER type collets have two clamping zones and are distinguished by the presence of a through hole, which allows you to fix a drill bit or milling cutter with a shank of any length.
