I have a nichols Horizontal miller with a 40NMTB taper. The question is, are other 40 tapers the same, such as a CAT40? I have seen other 40 tapers listed on E-bay that have some letters befor the 40. I don't have a clue as to wheather they will fit the 40NMTB.
Thanks for any enlightment that you fellows can give me.
