Which tool should not be used with a power vise?

The spiral reamer is designed to smooth and enlarge the inner diameters of pipes, typically used in hand operation rather than being subjected to power tools. When using a power vise, tools that are not specifically designed for power operation can be dangerous. The power vise applies a significant amount of torque and pressure, which can lead to mishandling or damage of a delicate tool like a spiral reamer. Moreover, using a spiral reamer in a power vise can cause it to bind or break, leading to potential injury or tool failure.

In contrast, tools like a pipe wrench, hack saw, and adjustable pliers are generally sturdier and can handle the force applied by a power vise safely. They are meant to grip, cut, or manipulate materials effectively under the conditions provided by a power vise, showcasing their applicability in that context.
