This part of ISO 12164 specifies dimensions for receivers with taper and flange contact surfaces for hollow taper shanks in accordance with ISO 12164-1 to be applied on machine tools (e.g. turning machines, drilling machines, milling machines and grinding machines). A range of sizes is specified.
This part of ISO 12164 specifies two styles of receiver. Style A is for automatic tool exchange and style C is for manual clamping which is achieved via holes in both the receiver and the tool shank.
