HSK-A tool holders
HSK-A Shrink Fit Holders – HSK-A50, HSK-A63 and HSK-A100 (DIN 69893-1)
A shrink fit holder clamps h6 carbide tool shanks by thermal shrink fit, loaded with a heat shrink machine. PTP makes them with an HSK-A shank (DIN 69893-1 / ISO 12164-1) in HSK-A50, HSK-A63 and HSK-A100: bores Ø6–32 mm, gauge lengths 80–120 mm, 28 ordering codes in all. HSK-A tapers are clamped by the spindle itself, so no pull stud is needed. Taper AT3 or better, TIR 0.005 mm max, balanced G2.5 @ 25,000 rpm.

Questions about HSK-A shrink fit holders
Does an HSK-A shrink fit holder need a pull stud?
No. The spindle clamps the HSK-A taper from inside, so there is no pull stud. For through-spindle coolant the holder takes an HSK-A coolant tube: 47CTHA050 for HSK-A50, 47CTHA063 for HSK-A63 and 47CTHA100 for HSK-A100.
What goes with an HSK-A shrink fit holder?
A heat shrink machine, to load and unload the h6 carbide tool shank.
