Dimensions of the Morse Taper

The most common Taper in use on the Lathe is the Morse Taper, although there are many other types of Taper in use, these are generally for use in Mechanical and Precision Engineering Disciplines, such as Collet Chucks for Milling, and therefore not often encountered by the Woodturner.

The Standard Dimensions for the various Sizes of the Morse Taper Shank are given below.

All dimensions are in inches with Metric [mm] equivalents for major dimensions.

D1 = Large End of Taper Diameter.

D2 = Small End of Taper Diameter.

α = Angle of Taper.

L  = Length of actual Taper Section.

Overall Length of the Morse Taper will depend on the individual designs from the Manufacturer and the variance for items attached to the Morse Taper.
