Terms of the Trade: What Is a Rotary Saw? Terms of the Trade: What Is a Rotary Saw?

Also known as a spiral cut saw or a cut out tool, a rotary saw spins a cutting implement around an axis, cutting out lines and patterns in wood, drywall, aluminum, etc. What's unique about a rotary saw is that it eliminates the need for a pilot hole (a small hole that allows another tool to be inserted for a larger cut). The spinning does the cutting, so the tool can be applied directly to the surface. This type of power tool usually has different bits that can be attached for various types of work and angles.
