The GoSports 6 inch hole saw is a premium construction grade tool that cuts perfect 6 inch diameter holes, no matter what your project. We were frustrated by the other cheap hole saw products that broke after only one use, so we designed our own that is built to last. The bits are perfect for a wide variety of projects, including cornhole boards, air ducts, ceiling lights, speakers, and more. The bit universally attaches to any 3/8 in or 1/2 in drill and has a blade depth of 7/8 in. The saw can cut through wood, drywall, plaster, and soft metals. Adult use only and always wear appropriate safety gear when using.
