An HSK (Hohl-Schaft-Kegel) Tool Holder is a hollow-shank taper system that provides dual contact (taper + flange) between the spindle and holder. This design ensures excellent rigidity, minimal runout, and stability at very high spindle speeds. Asmita Industries manufactures HSK tool holders using premium alloy steel with precision grinding to meet demanding production requirements.
