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-A form is probably the most common in the HSK family, and features drive slots which serve both to increase torque capability and provide rotational indexing (unequal slots). External features provide an interface for automatic tool change grippers and carousels. There is a bore milled directly into the side of the interface for RFID chip placement, and a threaded internal passage for coolant-through operation.

The Weldon interface utilizes a straight bore and one or more setscrews to grip the tool shank, and was invented circa 1918 by Carl A. Bergstrom in Cleveland, USA. Although seemingly crude and archaic, this style of tool holder interface often outperforms more modern systems when it comes to extremely heavy machining loads, and cannot be beat for simplicity.
