Drill tool : what is MT2 etc. for sizing of tool? how to convert it in mm?

Answer 1

MT stands for "Morse Taper".

MT2 means Morse Taper number 2.

Morse tapers can have two types of ends:

-tang to facilitate removal with a drift

-threaded to be held in place with a draw bar .

The taper itself is roughly 5/8" per foot, but exact ratios and dimensions for the various sizes of tang type tapers are different.
