Description

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 peripherally grooved flange for automatic tool change in turning machines with a gripper for HSK Type T;
Type TA has 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 bore holes in the hollow shank taper.
