HSK Morse taper holders — adapters from an HSK50A, HSK63A or HSK100A spindle to an MT1 through MT5 tool, in 24 models. Two forms, and picking the wrong one is the usual mistake. MTA takes the plain tanged Morse taper shank of a drill or reamer, held on the taper alone. MTB takes the threaded-tail form and pulls it up on an internal draw thread. The flange sets the ceiling: HSK50A stops at MT3, HSK63A at MT4, only HSK100A carries MT5. The HSK shank is cut to ISO 12164, the same standard Europe calls DIN 69893. Unsure which Morse taper your tool is? Measure the small end of its shank against the d2 column — 12.065mm is MT1, 44.399mm is MT5.
