Tapers

Jacobs Morse Brown & Sharp

Tips for ordering drill chuck arbors:
Most often, a drill chuck arbor has a longer end that is either a straight shank or a male Morse Taper to fit into a drill press. The other, shorter end of the arbor is a male Jacobs taper to fit into a drill chuck. If a drill press has a non-removable male spindle, the taper is usually 33 Jacobs Taper.
