Hollow taper interface with flange contact surface - Part 3 : dimensions of shanks for stationary tools

ISO 12164-3:2008 specifies dimensions for hollow taper shanks with flange contact surface (HSK) to be applied to machine tools (e.g. turning machines, turning-mill machines). A range of shank sizes is given.

ISO 12164-3:2008 specifies the shank of type T, which incorporates a grooved flange to enable automatic tool exchange. The tools may also be exchanged manually via a hole in the shank taper. The torque is transmitted at the tail end of the shank through keys as well as friction.
