Morse Taper

Morse taper is a standardized system of self-holding, self-releasing tapers used in machine tools, such as mill drill machines or lathes, to securely connect toolholders or workpieces to the spindle or arbor. The Morse taper system features a shallow, conical angle, typically between 1.5 and 2.5 degrees, that provides a tight, friction-fit connection capable of transmitting torque and resisting axial forces. Different sizes of Morse tapers are available, denoted by a number (e.g., MT1, MT2).
