$25.00

Both mandrels are #2 Morse taper, both have a 3/8"x16tpi thread and the step or collar that is the same diameter as the stoppers. The differences are detailed below: #2MT-A 3/8" x 16 tpi screw with a "slit" in the threads so it is self tapping (**see bottom picture on left). The Morse taper end is threaded for a 1/4" x 20 tpi drawbar. ** the section between the Morse taper and the section that is the same diameter as the stoppers is 7/8" diameter. This can only be used in the Morse taper.
