Cut a variety of hole sizes in ceilings, walls, floors, and other surfaces without all the mess. These hole saws have two adjustable blades that bite into drywall, plaster, plastic and wood to make larger holes than a drill bit alone. They also have a clear debris shield to catch flying chips and collect dust. The shield’s rubber seal maintains contact with the surface you’re cutting, which keeps the debris contained and prevents damage to surrounding material. Use these hole saws to make perfectly round holes to install a range of cylindrical items from cables to doorknobs to recessed lighting. Power them using a drill press or portable drill.
