Cutting back cinderblock wall?

[Vinny]

On the side of my house, there is a second gate that leads to the back yard. I took the gate down, but now I want to cut back this cinderblock wall so it's wider and will let me move bigger items into the shed I'm building. I don't want it completely gone since it looks like it's part of the wall that divides. My property with the neighbors. It's 4 inch wide cindeblocks, hollow in the middle, stacked about 5 feet high
I'm thinking of just renting a large disc cutter, but any other options? I've seen Sawzall blades for this, but would they last all the way through?

You'll likely have a lot smoother cut w/ the disc... and if there's a lot of steel in the block, it will be slow going w/ a sawzall. Diamond blades hate steel. I'd go w/ the disc.

I think you would have to remove the bigger “post “ and cut down the thinner wall section. Make new footer and rebuild “post”

I bought a lightly used gas 14” chop saw that came with a diamond blade. Over the years I have used both diamond and and abrasive wheels. The diamond wheels are expensive and, although they last longer than the abrasive wheels, I lean to abrasive as I think the cost per linear foot of cut is less.

Use the water attachment to keep the dust down, use eye protection, a dust mask, and hearing protection, if for no other reason to keep the dust out of your ears.

You can rent the saws at HD or your local rental yard.

My saw is gas, but the industry seems to be evolving to battery.

Mine is a Makita, but Stihl, Husqvarna, and I think even Harbor Freight offer them.

I wouldn’t waste my time with a hand held angle grinder, especially since I know of no water attachment for dust control.
