What type of chisel is specifically designed for cutting metal without heat?

A cold chisel is specifically designed for cutting metal without the application of heat. It is made from a hard steel alloy that can withstand the high stresses encountered when cutting through harder materials. The cutting edge of a cold chisel is often ground at a specific angle to provide an effective cutting action while retaining its sharpness during use.

Cold chisels are commonly used in metalworking to shape and cut metals such as steel, iron, and aluminum. Unlike chisels that might be used in woodworking or other applications where heat might be an element, a cold chisel operates effectively at room temperature, making it ideal for tasks where heating the metal is not practical or could interfere with the desired properties of the metal.

The other types of chisels mentioned, such as round chisels, socket chisels, and mortising chisels, are designed primarily for woodworking applications. They are not suitable for cutting metals as they do not possess the necessary hardness or design to perform well on harder metallic surfaces.
