HSK-A Morse Taper Adapters – HSK-A50, HSK-A63 and HSK-A100 (DIN 69893-1)
A Morse taper adapter holds Morse-taper-shank drills and reamers in the machine spindle. PTP makes them with an HSK-A shank (DIN 69893-1 / ISO 12164-1) in HSK-A50, HSK-A63 and HSK-A100: MT1 to MT5, gauge lengths 105–200 mm, 18 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 @ 15,000 rpm.

Questions about HSK-A Morse taper adapters
Does an HSK-A Morse taper adapter 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 Morse taper adapter?
Drills and reamers with a Morse taper shank: MT1, MT2, MT3, MT4 and MT5.
