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-T form was developed in 2008 for use in multi-tasking and turning centers. It is essentially the same as HSK-A, except in that the drive slots are manufactured to a much tighter tolerance standard (ISO121 165-3:2008), which provides better rotational accuracy crucial for positiong turning tools consistently. In rotating applications, HSK-T and HSK-A are fully interchangeable.
Company History:
The company is a result of the merging of Metallwerk Plansee GmbH (Austria, 1921, later 'Plansee Tizit') and CERAMETAL (Luxembourg, 1931). The name Ceratizit was created by combining their names in 2002. Both founding companies originally produced molybdenum wire and tungsten lightbulb filaments, and were pioneers in commercial cemented tungsten carbide (since as early as 1929!) and their metal working / cutting tool product lines currently add up to over 80,000 items!
