What is a "hole saw"?
A hole saw is a tool used to cut large, round holes in various materials like wood, metal, or plastic. It consists of a circular saw blade attached to a central drill bit, which helps guide the tool while cutting. Hole saws are commonly used for tasks such as installing plumbing pipes, electrical outlets, or creating large holes for ventilation. They are available in different sizes and are often used with a power drill for easier, faster cutting.
