Roto Zip

A Rotozip is a powerful handheld rotary tool, often called a spiral saw, used for fast, precise cutting in drywall and other materials like wood, tile, and metal, making it ideal for cutting out electrical boxes, light fixtures, and other openings in walls and ceilings. It looks like a drill but functions like a saw, using various high-speed cutting bits (zip bits) and often a guide-tip for control, allowing plunge cuts and detailed work that's much quicker than traditional saws.
