I have a concrete bunker on my property, 14x14. It has a narrow 24" door that I would like to widen. 6" thick concrete.

Think with a 7" concrete blade on a Skill saw I could make vertical cuts on both sides of the wall (same side of the doorway)? Or will it bog down or overheat?

Yeah, I saw concrete the other day with my own eyes.


No, it will work, wet down the dust, its not only hard on the saw, its hard on you, look up silicosis.

That should work, cool having a bunker, make a nice root cellar maybe or a sweet cabin of sorts.

I have cut a 6 inch vertical concrete wall before... to widen a doorway. As Brettny says, it is a tough job, but made easier with the right tool. Go to a rental place and get a 10 inch gas powered saw made for cutting concrete. It should have a place on it to screw in a garden hose. You need to run water on the blade the whole while you are cutting. Using an electric skill saw would be pretty dangerous when mixed with water! Don't know how old you bunker is but likely that concrete will be very hard. A gas saw with a diamond blade is your friend here.

I would do as Nobadays suggests. Rent a saw made to cut concrete. You will need a water supply, that is critical. Using a skilsaw for a job like that is not recommended. Maybe for cutting a concrete patio block or two, but not serious concrete like your bunker wall. And hope they did not use a lot of rebar

Thanks guys. I do have this Stihl saw I used on my paver project, just not sure I could hold it up for the time it would take. It has a14" blade and is pretty, um, exciting when it gets on the power band. It has a water hookup but I don't have the bottle and hose that goes to it.

TMT, what it is is more correctly a bomb shelter, per the original plans. My property had a house on it, built in 1960. All that remained when I bought it was the foundation and the shelter. As of a week ago it's now my carport.

Paulz... yep that is what I used, and yes it is pretty hard work to make a vertical cut. I had two arms when I did this years ago. Maybe counter-weighted rope and pulley system? Good luck on it!

If you dont care about how smooth the cut is and have more time than arm strength yes a circular saw will work ok. A gas or electric demo saw is what i would use if i cared about the finish.

I have a 10in worm drive circular saw. Man is that thing dog slow to cut concrete.
