What cutting tool has an adjustable blade depth and two blade guards?

The circular saw is designed with an adjustable blade depth, allowing the user to set the depth of the cut based on the material being worked on. This feature is essential for achieving various cut depths and helps in cutting through different thicknesses of material efficiently. The inclusion of two blade guards enhances safety by covering the blade when it is not in use and protecting the user from accidental contact with the blade during operation. These safeguards are crucial in maintaining a safe working environment and minimizing risks associated with power tool usage.

Other tools mentioned, such as the table saw, band saw, and reciprocating saw, serve different functions and may not feature the same combination of adjustable depth and dual blade guards, making the circular saw the correct choice for this specific question regarding cutting tools.
