Which saw uses interchangeable blades for cutting wood, metal, masonry and can spin at about 6,000 RPM?

• A. Circular saw
• B. Hammer drill
• C. Rotary Saw
• D. Angle grinder

Answer: (C)

Having interchangeable blades and a high-speed rotation lets a single tool cut wood, metal, and masonry by switching to the appropriate blade for each material. The tool described is the rotary saw, designed to accept blades for different materials and spin fast enough to cut through them—around 6,000 RPM on common models. This versatility to switch blades for distinct materials and the high RPM are what set it apart from other cutspecific tools. While other tools can sometimes cut multiple materials with special blades, the rotary saw is the one built around quick blade changes for wood, metal, and masonry and the speed to drive through those materials.
