Which type of saw is used to cut metallic materials?

• A. Hacksaw
• B. Jigsaw
• C. Circular saw
• D. Reciprocating saw

Answer: (A)

Cutting metal requires a tool whose blade is designed to cut hard materials without bending or wandering. A hacksaw is built exactly for that purpose. It uses a narrow, hardened blade with fine teeth held under tension in a rigid frame, which keeps the blade straight as you push back and forth. The tooth design and blade tension let it bite through metal cleanly, making precise straight cuts in bars, tubes, pipes, or plates. The other saws aren’t as well suited for metal cutting. A jigsaw relies on a flexible blade and is intended mainly for curved or intricate cuts in wood (and sometimes thin plastics); it doesn’t provide the straight, controlled cuts you want on metal. A circular saw is great for wood and can cut metal only with specialty blades and setups, but it’s less precise and less practical for metal stock. A reciprocating saw is powerful for rough, demolition-style cuts and can work on metal, but the results are usually rough and less controllable for clean, straight stock cuts.
