Which tool is used to hold work securely when operating a machine?

• A. machine vice
• B. Scroll Saw
• C. Ball Pein Hammer
• D. Belt Sander

Answer: (A)

Holding work securely during machining is essential for accuracy and safety. A machine vice is the tool designed for this role. It clamps the workpiece firmly between two jaws, with one jaw fixed and the other moved by a screw to tighten. This setup provides a rigid hold that resists the cutting forces and keeps the work in the correct position throughout the operation. It can be precisely aligned with the cutting line and is mounted on the machine table for stability. The other options don’t serve as the securing device: a scroll saw is the cutting machine and isn’t a dedicated clamping tool; a ball pein hammer is used to shape or strike metal, not to hold it; a belt sander is a finishing tool and requires the work to be held by clamps or a vice, not by the sander itself.
