HSK-A tool holders
HSK-A ER Collet Chucks – HSK-A50, HSK-A63 and HSK-A100 (DIN 69893-1)
An ER collet chuck holds round-shank cutting tools in a DIN 6499 ER collet, closed by an ER clamping nut, for drilling, reaming and milling. PTP makes them with an HSK-A shank (DIN 69893-1 / ISO 12164-1) in HSK-A50, HSK-A63 and HSK-A100: ER16 to ER40 collets, gauge lengths 80–180 mm, 34 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 ER collet chucks
Does an HSK-A ER collet 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 ER collet chuck?
DIN 6499 ER collets (ER16, ER20, ER25, ER32 and ER40), the ER clamping nut of that size (slotted 36CCNER16, 36CCNER20, 36CCNER25, 36CCNER32 and 36CCNER40; hex ER-A 36CCNER16A and 36CCNER20A) and, for coolant-through tools, an ER sealing ring (ER16, ER20, ER25, ER32 and ER40).
