How to Remove an Arbor From a Drill Chuck

Drill chucks are pressed into the drill press arbor, which in turn mounts inside the spinning shaft of a drill press. A drill press allows for the use of multiple different-sized drill bits. However, each drill chuck has a limitation in the largest size. For example, a 1-inch drill bit will not fit into a drill chuck with a maximum size of 3/8-inch. If you need to use a drill bit this size, you must remove the drill chuck from the arbor so you can install a larger drill chuck. With the correct tools, you can quickly remove the drill chuck from your drill press.

Instructions

1. • 1

     Disconnect the drill press from its power source to prevent it from coming on while you remove the chuck.

   • 2

     Press a drill chuck removal wedge on opposite sides of the drill chuck between the top of the chuck and the bottom of the arbor.

   • 3

     Tap on each wedge in an alternating pattern with a hammer until the chuck frees from the arbor. Hold the chuck with one hand as you hit the wedge with the hammer in the other hand. This will keep the chuck from falling and becoming damaged.
