Final answer:
The appropriate device to clamp round, square, or irregular shaped pieces is a universal chuck or an independent chuck (4-jaw chuck), which has independently adjustable jaws to accommodate different shapes.
Explanation:
The work holding device best used to clamp round, square, or irregular shaped pieces is a universal chuck (also known as an independent chuck or 4-jaw chuck). This device allows each of the four jaws to be adjusted independently, which facilitates the clamping of various shaped objects securely for processes like machining on a lathe. Universal chucks are particularly useful when dealing with non-cylindrical or asymmetrical workpieces.
