What type of chisel is used to cut a narrow square-shaped groove in a piece of mild steel?

  1. Flat chisel

  2. Cross chisel

  3. Cape chisel

  4. Diamond chisel

The correct answer is: Cape chisel

A cape chisel is specifically designed for cutting narrow grooves or slots in materials, making it the ideal choice for creating a square-shaped groove in mild steel. The chisel has a flat cutting edge and is typically employed in metalworking for tasks that require precision in shaping or engraving. Its design allows it to reach into tighter spaces compared to other types of chisels, enabling the operator to make clean, defined grooves without damaging the surrounding material. This capability is essential when working with mild steel, as the material can be textured or shaped with fine detail, which is achieved by the focused cutting edge of the cape chisel. Using this tool effectively allows the machinist to control the depth and width of the cut with precision, ensuring that the groove meets the necessary specifications for the project.
