1 Scope
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.
