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 and grinding machines).
This document specifies three types of shanks:
— types AS and ES have a peripherally grooved flanges for automatic tool change;
— type CS has a flange without peripheral groove and can only be changed manually.
HSK types AS and ES can also be changed manually via radial bore holes in the hollow shank taper.
This document provides information for dynamically balanced HSK‑AS and HSK‑CS shanks balancing according to ISO 16084.
