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-F form is similar to E in that it is intended for high speeds, however it uses a cone one size down (or flange one size up, if you like). This provides a larger axial support surface and is more stable compared to HSK-E of the same cone size.
