This document specifies dimensions for receivers with taper and flange contact surfaces for hollow taper shanks (HSK) in accordance with ISO 12164-1 to be applied on machine tools (e.g. for turning, drilling, milling, grinding and combinations of them).

This document specifies three types of receivers:

.     type A for automatic tool change;

.     type C for manual tool change only, via radial holes in both the receiver and the tool shank;

.     type E for automatic tool change.

NOTE 1        The receivers of types A, C and E fit the HSK shanks of types A, AB, C, CB and EB (according to ISO 12164-1).

NOTE 2        HSK shanks of types A, AB and EB can also be changed manually.
