The best way to cut through a ceiling constructed from drywall is with either a reciprocating saw or a drywall handsaw. These are two different devices with very sharp blades on the end made for performing the job at hand.
When you need to cut through the drywall on your ceiling, you should start out by marking exactly where you want the cut to be made. You cannot stab the saw blade through the drywall. You have to make a starter hole the blade can slip through.
This article will teach you the best way to use both of these tools to cut out a section of your drywall ceiling.
Know what is in the path of the blade before cutting into any ceiling materials with any cutting tool. Failure to do so could be catastrophic.
Using A Reciprocating Saw
The reciprocating saw has a changeable blade that moves back and forth at a very rapid pace with the aid of an electric motor. Much the same way a tattoo gun works. The saw has a short throw, but the user must be highly aware of what is on the other side of the drywall being cut at all times.
Many homes have conduit, exposed wiring, insulation, ductwork, even pressurized gas lines running through the space above the ceiling. Some even have furnaces and other appliances in the attic. The utmost caution must be taken to ensure the blade doesn't cut into or strike anything it shouldn't. If you don't know what's on the other side of the cut you'll have to use more finesse should you choose to continue. In which case your needs might be better served by using a box cutter that barely penetrates through the drywall.
You'll be working over your own head so the more comfortable you are doing it the easier it'll be. You'll need safety glasses, a dust mask. good ventilation and a sturdy ladder, or scaffold to proceed. It's always a good idea to have a helper standing close by.
When you turn on the saw, work as slowly and carefully as possible. It can be difficult to control the saw, and the blade moves fast. This could quickly lead to mistakes and safety hazards, even a major catastrophe. Don't become a statistic.
Starting The Cut
This is where the drywall handsaw comes in handy. This tool will make the cut as well as anything will. The tip is very sharp and made for biting through the drywall. Place the tip on the mark you wish to start the cut and work it into, and then through the drywall. All the while taking care not to cut into your lines. Once the tip is through you can cut out a slot for the blade of your reciprocating saw to slip into. Follow the lines you laid out and make the cut.
