How To Determine Your Machine's Morse Taper Size

How To Identify the size Of Your morse Taper:

Morse Tapers (MT) may be identified either by measuring the large, or the small diameter, the length, or the taper per inch. On the female MT (usually in a machine spindle) it’s difficult to measure the small diameter, the length, or the taper since it’s inside the spindle. Measuring only the largest diameter of the hole at the face (or gage line) of the spindle is all you need to find the correct MT size.

Shanks can also be identified by the gage diameter, but since the entire shank is accessible, the small diameter, length and taper per inch can be measured as well. Once you measure your Morse Taper, use the chart below to determine the correct MT size to ensure you are selecting the correct arbors and holders, adapters, and drill chuck arbors.
