Which of these does not create wood chips when used?

The jigsaw is the tool that does not create wood chips in the same way the others do. When a jigsaw is used, it primarily makes cuts in the material, and while it does produce dust and small shavings, it does not efficiently create wood chips like the other tools listed.

Drill presses, routers, and planers are specifically designed to remove material from wood in a way that results in larger wood chips. A drill press creates chips as it drills holes into the wood, removing substantial portions of material. A router shapes wood, producing shavings and chips as it carves out contours or grooves. A planer smooths and flattens wood surfaces, slicing off material to create even boards, which results in chips being formed.

Each of these tools operates fundamentally differently from a jigsaw, which primarily involves rapid back-and-forth motion of the blade to make cuts without generating significant wood chips. Thus, the jigsaw is distinctly different in its operation regarding chip production.
