HSK-A Hydraulic Chucks – HSK-A50, HSK-A63 and HSK-A100 (DIN 69893-1)

A hydraulic chuck clamps the tool shank through a hydraulic membrane for finishing, drilling and reaming. PTP makes them with an HSK-A shank (DIN 69893-1 / ISO 12164-1) in HSK-A50, HSK-A63 and HSK-A100: bores Ø6–40 mm, gauge lengths 75–125 mm, 29 ordering codes in all. HSK-A tapers are clamped by the spindle itself, so no pull stud is needed. Taper AT3 or better, TIR 0.003 mm max.

Questions about HSK-A hydraulic chucks (HYD)

Does an HSK-A hydraulic chuck 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 hydraulic chuck?

Hydro intermediate sleeves (HIS) reduce the Ø12, 20 and 32 mm bores to smaller tool shanks, Ø3–25 mm.
