What is the best way to cut through 4 layers of drywall?

We are renovating a retirement home and need to cut through 4 layers of drywall.

some precise cuts to run wire, lights, fixtures, etc

Give the 10 to Bubba.

No other answer is needed.

They can be rented or purchased for under $100, and if the job is large enough BUY one, or more. I have 2,,, a Porter, and a Milwaukee,,, both are higher end, but are workhorses. BTW,,, they are corded.

A normal blade length is approx. 4 inches, but longer are sold, even singley. To avoid a lot of trash and rough edges, use a fine tooth blade. I assume you'll have power shut off,,, and/or know where wiring might be located?

by the sound of it just tear it down with a sledge hammer or chainsaw

with a reciprocating saw.

use a sawzall it the best tool to have and you can use it everywhere. you can get different blakes for it to do different things with it , too

sawzall as long as the conditions are right.::no electric or plumbing.stuff like that in the way.
Or use a utility knife and go one layer at a time.
Or just sledge it if you want it all gone.

A sledge hammer!

4 layers sounds like the contractors had a field day doing work for place use a saw or sledge hammer depending on how much you want to save or take out
