| 1 | 0.4750 | 0.3690 | 0.7500 | 2.5625 |
| 2 | 0.7000 | 0.5720 | 0.8750 | 3.1250 |
| 3 | 0.9380 | 0.7780 | 1.1875 | 3.8750 |
| 4 | 1.2310 | 1.0200 | 1.2500 | 4.8750 |
| 5 | 1.7480 | 1.4750 | 1.5000 | 6.1250 |
| 6 | 2.4940 | 2.1160 | 1.750 | 8.5625 |
| 7 | 3.2700 | 2.7500 | 2.6250 | 11.6250 |
NOTE: At times, the female Morse Taper cavity in a machine may be slightly smaller than the maximum diameters shown above. This is because the MT tooling often extends a bit past the end of the spindle that is receiving the Morse Taper Tool. For Instance, the “A” dimension for a MT2 female cavity may actually measure 0.695″ rather than 0.700″ in extreme cases, etc. The differences in dimensions grow wider as you go from MT0 to MT7.
