Background Information:

The HSK system was invented in Germany in the 1990's and is now very commonly found in European machine tools and spindles. HSK stands for "Hohl Shaft Kegel" - "Hollow Shank Taper", and as the name implies this type of interface has a cavity running through it. Unlike classical 'pull-stud' designs (CAT, BT, SK etc), HSK uses an internal drawbar mechanism which results in clamping force increasing with rotational speed. Additionally, the form features dual contact; on an axial face and the cone (1:10), which puts HSK in the upper echelons of tool holder performance.

The HSK-E form is designed for extreme speeds; with all sources of unbalance removed. This type still has a ring feature for automatic tool changing, but does not have any feature for integrating RFID chips
