Which tool is typically used to cut straight lines in sheet metal?

• A. Drill press
• B. Lathe
• C. Grinder
• D. Shear

Answer: (D)

Straight, clean cuts across sheet metal are produced by a shear. A shear uses a straight-blade action that shears the metal along a defined line, which gives a precise, noteable edge and can be guided with a fence or back gauge for long, consistent cuts. The other tools have different jobs: a drill press makes holes, a lathe shapes material around a rotating axis, and a grinder removes material and finishes surfaces but doesn’t provide a controlled straight cut across the sheet. So for cutting straight lines in sheet metal, the shear is the appropriate tool.
