Which tool would you use to cut wood using a rapidly rotating toothed disk?

• A. Circular Saw
• B. Router
• C. Chipping Hammer
• D. Socket

Answer: (A)

A circular saw is the tool that matches a rapidly rotating toothed disk for wood cutting. Its blade is a circular disc with teeth around the edge that spins quickly to shear wood fibers for straight cuts. The router uses a rotating cutter bit (not a full circular blade) and is typically used for edges, grooves, or profiles. A chipping hammer is for masonry or concrete, delivering hammer blows, and a socket is a wrench-like tool for turning fasteners. So the distinctive toothed circular blade points directly to the circular saw.
