What tool is used to remove a tapered shank twist drill from the drill press spindle?

1. Drill socket

2. Drill drift

3. Collet wrench

4. Extraction tool

The correct answer is: Drill drift

The tool specifically designed to remove a tapered shank twist drill from the drill press spindle is known as the drill drift. A drill drift is a tapered tool that can be inserted into the slot of the spindle to separate the drill from its mounted position. The design allows for a careful application of force to disengage the drill without damaging the spindle or the drill itself. When using a drill drift, the operator can easily knock out the compressed fit of the tapered shank, ensuring a smooth removal process. This tool is essential in a millwright's arsenal because it simplifies the task and increases safety while handling drill bits, which can be heavy and awkward. Other tools listed may serve different functions; for instance, a drill socket is a holder for specific types of drill bits, a collet wrench is used to tighten or loosen collets in machinery, and an extraction tool generally refers to a broader category of tools for removing various components. Thus, they do not perform the specific action needed for removing a tapered shank from a drill press spindle as effectively as the drill drift does.
