Greenlee 35713 6-3/8 Steel Toothed Recessed Light Hole Saw

Using the Greenlee 35713 hole saw is quite simple. First, make sure you have a power drill and the Greenlee Arbor 37156 (which you'll need to buy separately). Attach the arbor to the saw and then to the drill. Select the appropriate blade - the steel - toothed one for plywood, wood, acoustical tile, and ceiling tile, or the carbide - grit one for drywall, plaster, and stucco. When cutting, apply steady pressure and let the saw do its work. Don't force it too hard. As for maintenance, after each use, clean the blade to remove any debris. Keep it in a dry place to prevent rusting. If the blade gets dull, you can consider replacing it with the interchangeable blades that come with this product. And always follow the safety instructions of your power drill when using the saw.
