This document specifies dimensions for receivers with taper and flange contact surfaces for hollow taper shanks (HSK) in accordance with ISO 12164-5 to be applied to machine tools (e.g. machines for turning, drilling, milling and grinding). This document specifies three types of receivers: —     type AS for automatic tool change; —     type CS for manual tool change only, via radial holes in both the receiver and the tool shank; —     type ES for automatic tool change. NOTE 1        The receivers of types AS, CS and ES fit the HSK shanks of types AS, CS and ES (according to ISO 12164-5). NOTE 2        HSK shanks of types AS and ES can also be changed manually.
