ISO 12164-1:2023 Scope

This document specifies the dimensions of hollow taper shanks with flange contact surface (HSK). These shanks are the male part of the interface to the machine tools (e. g. milling/drilling, turning and grinding machines).

This document specifies five types of shanks:

     types A, AB and EB have a peripherally grooved flange for automatic tool change;

     types C and CB have a flange without peripheral groove and can only be changed manually.

HSK types A and AB can also be changed manually via radial access bore holes in the hollow shank tapers.

This document provides information for dynamically balanced HSK‑AB and HSK‑CB shanks balancing according to ISO 16084.
