This document specifies the dimensions for 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 three types of shanks:
—     type T has a peripherally grooved flange for automatic tool change in turning machines with a gripper for HSK type T;
—     type TA has a peripherally grooved flange for automatic tool change in milling machines, enabled (designed) for turning, with a gripper for HSK type A or AB;
—     type U has no peripheral groove flange and is designed for manual tool change in turning machines.
HSK types T and TA can also be changed manually via radial access bore holes in the hollow shank taper.
