Cutting through Drywall Ceiling


Hello,
I am installing can lights in the kitchen and need to cut a strip of drywall out for the wiring. The strip will be about 12' long and 10" wide. Has anyone used a circular saw set to a 5/8" cut depth to do this? I am afraid to use a drywall saw as I may cut into something. Thanks.

A circular saw will make a huge mess...for days. The dust will get into the heating system and will be a problem for a couple days. I would use a straight edge and a razor knife, then break out the drywall.

A 10" wide slot to run a wire
A ciruler saw to cut sheetrock, never!
Something very wrong if it needs to be that wide.
Tell us more why your doing it his way.
Is this a first floor in a two story house?

Investing in an inexpensive multi tool with a half round blade will make for a neat cut---but answer Joes question first---why the slot cut?

Sounds like the wiring needs to go perpendicular to the framing. The slot allows a drill to get into the bays to drill.

Hit the nail on the head with that one I'd bet!

I have flexable drill bits up to 6' long for this type of work.
A whole lot less mess.

Understandable as a contractor.
But the regular diy homeowner isn't going to have a tool like that available.

Jim Port is correct. The wiring is perpendicular to the ceiling joists. It is also a two story home. I was thinking if the drywall was 10" in width, the drywall patch would be eaiser to handle. Also, the 10" width would give me plenty of room to work in.

oh'mike, are you talking about something like a rotozip (sp) that has a sheild that covers half the blade. I have an old rotozip that uses a drill bit looking tool. I use it for cutting circles and such. I will have to see if I can get an attachment. I was hoping to get something I could attach a shop vac to. Thanks.

He's talking about a tool like this.

Look at the top left. A whole lot less dust then a Roto Zip.

joecaption and MT Stringer, Thanks for the links. I have seen these at Lowe's but never paid any attention to them. I will see if I can find a youtube video showing it cutting drywall. It looks like it might just be the ticket. Thanks to all that replied.
Best Regards,

It's one of the most usefull tools I own, I have 2, or the Rockwell multi crafters and love them.
It goes through drywall like hot butter and has hundereds of other uses.
It would be far more accurite and at least 10 times faster then a razer knife.

The Harbor freight model comes with a blade that resembles a half moon. It oscillates back and forth, thus cutting your drywall. A helper with a shop vac would help reduce the dust. You would be done in no time.

Good luck.
Mike
