Which tool is commonly used to create perfect circular cutouts in drywall?

1. Jigsaw

2. Hole saw

3. Utility knife

4. Router

The correct answer is: Hole saw

The tool most commonly used to create perfect circular cutouts in drywall is indeed the hole saw. A hole saw is specifically designed to cut circular holes in various materials, including drywall, efficiently and accurately. It consists of a cylindrical blade that allows for precise cutting, which is ideal for making clean and smooth circular openings, such as for electrical outlets or light fixtures. While other tools like a jigsaw can be used for cutting shapes in drywall, it may not achieve the same level of precision for circular cuts. Utility knives are primarily used for scoring and straight cuts rather than precise circular cutouts. A router, while it has applications for shaping and hollowing out materials, is not typically the go-to tool for making circular openings in drywall due to its complexity and the specific skill required to use it for that purpose. Thus, for round cutouts, the hole saw stands out as the optimal choice, reinforcing its position as the most suitable tool for this specific task.
