Home / Products /Clamping Technology / Tool holders / HSK series
HSK has become the standard interface in metal machining operations. Clamping is done via taper and face contact – thus higher rigidity is achieved. Centering and axial fixing as well as repetitive accuracy is unmatched. HSK holders demand highest precision in the making.
> highest rigidity due to contact at taper and collar
> small & lightweight design
> high torque, high speed machining
> best precision & repetitive accuracy
