In this video, we review and demonstrate the Greenlee Quick Cutter Hole Saw. The Greenlee Quick Cutter Hole Saw attaches to any 3/8" electrical drill chuck so you can cut circular holes in ceiling tiles, drywall, and sheet rock. The blade distance from the center is adjustable, allowing you to cut circular holes between 2.5" and 7" in diameter. This hole saw is perfect for installing circle-shaped conduit, speakers, vents, lights, and more!
