What tool is specifically designed to remove broken screws without causing damage to the surrounding material?

The tool specifically designed to remove broken screws without causing damage to the surrounding material is the screw extractor. A screw extractor is a specially engineered tool with a tapered design that allows it to grip onto the broken screw securely. It typically features reverse threading, which means that when you turn the extractor counterclockwise, it grips the broken screw tighter and helps unscrew it from its position.

Using a screw extractor minimizes the risk of damaging the surrounding material, as the tool is designed to fit snugly into the broken screw while avoiding any unnecessary force that might harm adjacent components. This makes it an ideal choice for situations where precision and care are needed to remove a broken fastener without compromising the integrity of the surface or structure surrounding it.
