Which statement about water jet cutting is true?

• A. It leaves burrs
• B. It uses a laser to cut
• C. It cuts with a high-pressure water jet and leaves no burrs
• D. It cannot cut textiles

Answer: (C)

Water jet cutting works by directing a high‑pressure stream of water at the material (often with an abrasive added for toughness). This method removes material by erosion rather than tearing with a blade, and because there’s no heat involved, the cut is clean and does not create burrs or heat‑affected distortion. That’s why it’s true that it uses a high‑pressure water jet and leaves no burrs. The idea that it’s a laser is incorrect, since it relies on a water stream, not light. And textiles can indeed be cut with a water jet, so the claim that it cannot cut textiles is false.
