Basic Rotary Tool (1 of 5)

A basic rotary tool used as a drywall cutout tool has a single speed switch, a collet that holds the bit and a depth guide for use with different drywall thicknesses. The depth guide also acts as a base, riding against the drywall as you go through the cut.

When using a spiral saw to cut around an electrical box, plunge into the wall and find the edge of the box. Then, use the box as a template to guide the saw. The tip of the spiral saw bit doesn't have any cutting capability; it cuts from its side. When plunging into metal, plunge the bit in while rocking it.
