A circular saw is a versatile power tool commonly used in woodworking, construction, and other applications to make straight and accurate cuts in various materials. The tool gets its name from the circular shape of the rotating blade. Circular saws come in different sizes and designs, and they can be handheld or mounted on a table or other support.

Repairing a circular saw may involve various steps depending on the specific issue you're facing. Here's a general guide for common circular saw repairs:
